Big city, small city, old city; now no city?

This will be a short post, but I might not get the chance to post again for several days.  I landed in Kunming, went to two smaller cities (Dali and Lijiang) with old/ancient towns that, at moments, make you think you walked through a legitimate time machine. Tomorrow I'm getting up early and going to Tiger Leaping Gorge, where I'll walk more than 20km over the course of 3 or so days, staying at guesthouses along the way. Wish me luck!
