Heyy,

No man you are not crazy (Or actually I am crazy and you are exactly like me...!),

I did the same thing, For my first backpacking trip I chose a 22mi trail for a two day solo hike, and camped over 9400ft. some said im crazy(http://www.yosemite.ca.us/forum/viewtopic.php?t=495), but that was the best. (Until I did a hike in sequoia -solo- and camped on the snow without any witer clothes and winter gear) have no words to describe the excitement. I think you had the same experience.

SOLO hiking is great.
