My two passions that pretty much dominate my life is downhill skiing in the winter and hiking in the summer. The best thing about both is that if I ever did get die hard serious about making my transition is that I could keep doing both with no issues. Though with hiking it would be nice to have a feminine body and those short shorts that really made my butt stand out, lol.
In the winter I work at ski resorts and pretty much ski every day and then in the summer I work at resorts that are in pretty cool places and do lots of hiking. Nothing like getting out in the wild and exploring.
I gave up skiing for poverty, but hiking is free, mostly. We've (usually 3 of us) made into the high country seven times this year - it was a very good year.
Hikers are a mostly different sort, more accepting than the lowland folks :) We've thoroughly enjoyed the experience of the outdoors, as well as the interactions with the people on the trails.
