Si,
I'll prob be out and about for at least one overnighter between 14/7 and 21/7 and want to explore along the Maekong east of Mae Sai as I've not really been up that way (apart from Chiang Khong once for the Laos crossing). It's unlikely to be more that 3 days/2 nights and I'll be on my Bonnie. Feel free to email/call if you are interested and I could put you up the night before the trip if that suited.
Cheers,
Pikey.
