It looks like a nice three day biking weekend coming up with Tomb Sweeping Day, a day many Taiwanese observe to clean the tombs of their ancestors and work a little geomancy to ensure luck and prosperity.
If you plan on riding this weekend remember to avoid areas near graveyards. There will be hundreds of people jostling their cars for parking and criss-crossing the roads with spirit money and incense. Passing graveyards at this time can be tedious, slow, dangerous, and not much fun.
I hope to get in one century ride and maybe a shorter recovery ride.
