This time of year is starting the thunderstorm season here in N. Texas as well, so be prepared for that. We just had some whoppers come thru here last weekend that caused several million dollars damage from hail/high winds/etc..
If you are going to the Mesquite rodeo, it will likely be fun.
If you are planning to go to Billy Bobs in Fort Worth (about 10 miles up the road form me) they have an indoor rodeo arena in the club, plus the mechanical bull for all the drunk locals and tourists to ride.
Oh yeah, don't wear your boots with your shorts on..
