Ok that is great information. I just may try that walk in option. As far as the diamox, the prescription was for 500mg 1/day. I have never been that dizzy on any hikes i have been on, including a summit of mt dana(13,053) I will check out the unused permit page. Thanks for the advice, this gives me some more options. The november option would have been pretty risky, and since i am not fully prepared for winter conditions..it would not have been a good option..
