Hey, wasn't sure where to post this...

As some of you know, I'm selling my 61 Apache because I have deemed it to be too much bodywork for a beginner such as myself. Anyhow, I found another 61 that I'm interested in, (found out about it here on Stovebolt!) but it's in Washington state, and I'm in Alberta, Canada. I've never bought a vehicle in the States before, and was wondering if anyone, Canadians in particular, have done this, and what does it involve?
