Patzcuaro, Mexico. Yesterday was my fourth ride in five days here. All of them have involved some amount of urban riding which has been a great way to see the town and a dizzying amount of visual, audio and olfactory experiences. All the roads are cobblestone and our hosts bikes that we are using are hardtails. And we are at 7000 feet and the rides have taken us up to around 8000 feet so plenty of huffing and puffing!
