Im actually in the planning stages of making a trip to montana with approximatelyme. I will say it is a pain in the butt planning something like this. We are planning on driving so that we can have total control over our environment and avoid possible exposures in airports and planes.
Now that I know what my mold symptoms are I can identify places in the past that I have gotten slammed, and one of the worst ones was in a plane. If you fly, use a respirator. Find out if anyone knows anything about the airport you are planning to fly out of or into.
From what Ive read, I would say maintain a good distance from any cities and try not to be within an hour or two drive downwind if you can.
There is no way I would consider using a cabin, even if someone said it was fine last year it might not be this year. Hotels are tough for the obvious reasons so I am going to avoid those too.
You never how sensitive you are until you are "clear" of mold and detoxing/detoxed, at least in my experience. Erik preaches the same as well.
To get past the mcs in a tent I will just be pitching the tent without the rainfly under a tarp to allow for plenty of ventilation. I have noticed that when I stay completely clear for even just a few days, which is the longest its happened for at this point, my mcs is alot better.
We are going for the entire summer to give us the best chance at desensitizing enough to be able to enter the "normal world" again and be able to survive through minor hits without our overall condition getting worse.
I would definitely think one slam would easily undo two weeks of being clear, and could even leave you in a state worse than one you have experienced so far, so BE CAREFUL!!!
Recovery is usually much faster at that point though.
Try not to take anything with you from the moldy environment. At the very least use new clothing and sleeping equipment. Make sure to thoroughly wash anything you are taking that is or isnt new and airdry it out in the sun.
Run hard objects through the dishwasher. Make sure to thoroughly dry everything then put it into new trash bags to avoid contamination until you get where you are going.
For food we are going to cook all of our own and to avoid having to go indoors I am planning on calling ahead and making an arrangement with the manager of the store. Im going to have them gather and ring up our food and handle the transaction in the parking lot.
If you are going for the best possible environment go for the desert, as long as everyone knows they can handle heat. I cant, hence Montana. Plus I just love the mountains and being in a place that makes me that happy and relaxed will help too.
Im also purposely going to the mountains so that I will have a place to do the "epo walk". Gain at least 300 feet of elevation on foot at a pace that gets you breathing but you can still talk. It must be done starting from the elevation you are acclimated to.
It causes the body to release a substance that has some awesome anti-inflammatory effects in just the way we need it and is supposed to have some amazing results. Shoemaker uses procrit to simulate this.
Make sure to take something to detox with if thats your goal, like CSM or charcoal. Be careful to avoid hits once you start if you havent yet, the "sicker quicker" phenomenon is very real and its a mother %$@#*^.
I cant recommend any particular places in the desert with any real expertise, Im just not that familiar, though Death Valley sounds good. It is very "clear" and has various elevations that you can stay at to stay in control of the temp of your environment and will allow you to do the epo walk.
Its only a couple hours from vegas too, the flight would be much more affordable. I think I remember somebody mentioning that the vegas airport has some mold, cant say for sure though.
Hope that helps!
Edit:
For sleeping gear, do not use down, it supports mold growth. Use a synthetic filled sleeping bag if a sleeping bag is what you use.
Buy it well in advance and keep it outside and open as much as possible so it can off-gas before you use it. Multiple cotton blankets is an option.
Make sure to sleep on an insulated mat if you camp. It gets cold out there at night.
If I get a chance I'll post a vid of my camping setup and link to it. If it doesnt happen this week its gonna be a couple weeks.
