Marko, seņor Dagoli posted this about the upcoming rodeo a couple of days ago - hope you know some spanish:
Rodeo is at the bullring, usually mid to late in the afternoon, after a big community all-welcome lunch (often birria) at the casino. Lots of good "street eats" to be had around town Looks like the rodeo will happen on Saturday, Sunday and Monday this year. It's mexican rodeo so events are not like one NOB but a really great experience. Dances at the casino with a different band each night, usually into the early morning hours. The town is generally rocking for rodeo days...
