After going to Siem Reap, I wrote up our border crossing experience for Tales of Asia. It's also a way to try to give back, since the site was so helpful to me and Claudia was we planned.

It's listed on the Cambodia Overland: Travelers' Reports.

Currently (as of the page's 26 Dec. update), our 2 cents are the third writeup on the page, under the heading "Overlanding on our own from Bangkok to Siem Reap (December 2003)"
