So I’m at least close. I got a photo of nearly the sunrise (I’m about 45 minutes late), on a nearly east/west road (off by about 15 degrees), on nearly the solstice (one day late). The photo is taken biking east along the Xindian River near Bitan Scenic Area, just south of Taipei. There’s a bicycle in the photo, and if you imagine a line from the photographer’s perspective that skewers the poor bicyclist, it nearly due east.
The photo was taken ar the beginning of our terrific day ride to Wulai, the best day so far of our tour of Taiwan.
