I'm considering a very spur of the moment trip. I'm meeting a friend in bangkok soon but we will part ways and I plan to stay in thailand until mid or late may. Considering renting a bike in Chang Mai to explore for approx 1-2 weeks in the region. Or flying to Hanoi and doing the same. I'm looking for interested bodies to join me, or suggestions for tour companies if I do it alone. No preference to on/offroad. I just want to see some scenery and take in some local culture.
