We will go there 23rd of November, I will take your old bike through Cardamom mountain from Pailin to Koh Kong, then Kirirom, Bokor to Kep. After that not figured out where to go but probably swing North through Bokor again and take it from there. I will possibly go up through Laos and out there, come up to Chiang Mai and let Dave download all from my GPS.
Looks like we will miss out by a month, but hey you should join the Cardamom Pikey you'd love that. Just looking at pictures and tales from that trail makes me smile, WOW what a ride
