Ultimately I'll be running across all of California from Nevada to the Golden Gate. I'm just about half done with with Western States Trail (but only contiguously from Sac as far as Rucky Chucky, see below):
Are you looking at this and thinking "what an archaic way to record this"? Me too! Now that I've gotten lost on the Western States Trail a few times (and seen 4 bears in the space of a year!) maybe it's time to get one of them thar GPS watches.
Other projects probably for after I retire: the whole CA coast (I already did San Diego County, now I only have 1,000 miles left!), the Siskiyou Trail, and of course the PCT. If I'm not bored and/or disabled by that point the Laurel Highlands Trail in PA might be nice too.
