Thanks, Synthia. Yes, I need to do more research on the visa aspects. All I know at this point is that American tourists don't need a visa in advance and Americans are very welcome. What I don't know is what the details would be if I went more often, stayed longer etc. I've been twice now with no problems but you're right, I shouldn't assume anything.

Healthwise, I assume at some point I'll have to quit skiing because of my knees. I already live at 5000 feet so I don't anticipate altitude being a problem.

I know that there are quite a few Americans already living in Colombia and I'm interested in hearing about their experiences.

Thanks for your reply!
