I am in Flores, Guatemala; I am here to wait for a package to come in the mail--a new pair of sports glasses, prescription, so I can play soccer along the way during my trip without worrying about them getting smashed. I can use them while cycling, too, and they protect against sand, dust and wind. The glasses should arrive in the next few days, hopefully. In the meantime, I am staying at Los Amigos Hostel, which costs 35 quetzales, or $4.50/night.
I visited Tikal a few days ago; the ride to it is pretty hilly. Mostly uphill there, downhill back.
