It seems to me the price and availabilty of a long term motorbike would be best on 17 or 18 April, rather than renting on the 15th when my gf takes the car back to Phetchabun. Am I correct?
Would someone be willing to give me a lift to a reputable motorbike rental location?
I'll gladly buy you a meal (within reason

) ) or beer or both while we're out.
