(Apologies for no espaņol..)

I'm heading to Guanajuato for two weeks at the end of February. I've had great ride experiences in both SMA and Oaxaca; but don't really know anything about the scene in Guanajuato. I found some info on Parque Xumu that looked pretty cool. Anyone have the low-down on their bike park?

Also looking to rent equipment and find a guide service. Help an amigo out? I can reciprocate with beers and trails if you're up in Seattle...
