Hi,
Timely subject, I'm just wrapping up 6 months in Guatemala City, I'm down here for my wife's TDY at the embassy. The driving here in the city is CHAOS, and that is being kind, I would never even think of riding a motorcycle in the city, that being said the rest of the country is much more relaxed. One thing that surprised me is the quality of the roads, we've been just about everywhere down here, including Belize, Honduras and El Salvador driving a car and I think most of them would be Spyder accessible. I even saw a Spyder driving around Antigua, GT unfortunately, I wasn't able to chase him down and find out his story. One word of caution, even though my wife speaks fluent Spanish and the people here have been wonderful, this is not the USA. There were too cars we used for our trips, on an armored embassy SUV and the other was a Corolla with limo-dark-tinting on all the windows, except the front. This is not a place that I would feel comfortable just jumping on the bike and taking off on a cross country ride. We are very exposed on motorcycles, much more so here, the gun laws are pretty friendly for foreigners, getting a permit takes a while if you don't know somebody, but they do approve them regularly. If anybody else has any questions I'd be happy to fill you in on what I've seen.
Take care,
Scott
