Actually, caitlin,
The last time I was there, I didn't feel as much difficulty as I did when I was there a few times before. My mom is on O2, and when I was first there for a week (it was a year ago May), I could tell when we were going to a higher altitude when we were sightseeing.
When I was there last Sept., I thought for sure I was going to have trouble, but actually, my wife had the reaction,and was on O2 for a couple of hours. I know that between the altitude and concern to stay hydrated, it's difficult to deal with, but it seems no matter what area you live in, there seems to be some sort of ecological difficulty.
Like Japan, no one ever told me how often earthquakes and typhoons would occur in Osaka. If I'd known that, I'd stayed in Detroit with all the snow storms, tornadoes and roads with potholes so big, Mac Trucks were known to fall into!
Colorado Springs is a beautiful place, I'm contemplating on moving there when I decide to leave Japan. Of course, my other reason is that I'll be close to family members.
And, well, Seana30; since I came across in another spool that Courtney is only 13, Childrens Hospital is probably more accurate for her. Though probably having a G.P. (general practicianer) from one of the bases can't be ruled out. Hope that helps...
