When I decided I was going to thru-hike the AT next year, I wasn't really aware of the PCT or the CDT. I've been doing some research on the other two and I'm now considering which one I really want to do.
Whilst the social aspect of the AT really appeals to me, the geography of the other trails, (CDT in particular) interests me more as it seems to be alot more mountainous.
I was hoping for some insight from fellow WB members as to why they chose the AT against the other 2. (Or maybe you did one of the others first and then the AT)
My dream is to do all 3 eventually.
