We went to Silver Spurs this year and had a great time. The Florida State Fair was in the grounds too with free entrance when you attended the rodeo.

They have 'Monster Truck Mayhem' and quite a few concerts, not sure of the dates but if you look at silver spurs website they will have all of the details (I cannot put the link here as it would be edited out).

It is a really nice arena, air conditioned etc. Just across the road from us too so no driving for us.
