Dang, now I also want to go there! What an awesome trip. How did you travel inside the country? Are there a bunch of flights inside the country or are there buses? (I have no sense of the scale of the country.)
Nepal is roughly the same area as Arkansas, so not all that big. While cities aren't generally that far apart, it took us 7 hours to drive the 60ish miles between Chitwan and Kathmandu because the roads are so windy and unkept. We hired a driver recommended by my local friend, and I wouldn't suggest trying to drive yourself unless you're familiar with driving in 3rd world countries... i.e. no signals and any signs/lines on the road are suggestions ;) If I went again I'd fly between cities (most have flights with very small planes); however, I'm really glad to have had the experience of seeing all the roadside villages, sights, and random herds of animals.
