In Texas we like to throw things: horseshoes, washers, beanbags. Although only one of those is fun to get hit with, so choose cornhole vs. horseshoe toss based on how good/bad your friends’ aim is.
We also like to trap stuff: try to lasso rope around stuffed animal cows. And, we like party favors, so give your guests a takeaway gift bag stuffed with Texas-themed lighters, Twang beer salt, some horse finger puppets, Texas Lottery scratch-offs, and steakhouse gift cards. Your guests will thank you later, because good manners are the most essential part of any Texas party.
