As I have not read this detail here on this forum I thought I would include it for anyones info.
Next Friday 3rd Dec & Saturday 4th Dec the "Chiang Mai Bike Week 2010" will happen at based around The Imperial Mae Ping Hotel.
From the event poster, it would seem there are some organised rides.
I enquired & got this back.
According to Bob Franck @ firstname.lastname@example.orgThe Charity ride to Mae Gnut Dam & Lunch at The Royal Ping River Resort will start at The Imperial Mae Ping Hotel at 9:30 AM With a Motorcycle Parade along the Ping River to Mae JO then north on 1001.
A second local event will leave Imperial Mae Ping Hotel at 11 AM to a local Orphanage School Wat Don Chon for Lunch.
Perhaps they will clarify if it is Fri 3rd or Sat 4th Dec?
