Band trip ideas for a small SD school

Hello band directors,

I am in my third year in South Dakota, originally from North Carolina. I am looking for fun and productive trip ideas for my high school band. This is being used in a big part a way to retain members and encourage students to stick with band. We currently have a concert band, it is small after a couple of director changes causing our numbers to go from 73 down to 20 students in the high school level. I have around 20-30 students in each 6-8 class which is around half of the entire class. The big difficulty I am up against is I am still new to this area and don't know anything within a trip distance. Coming from NC there were several options all within a few hours drive here it's going to be different. I am really looking for ideas so I can get cost goals for our newly formed booster group to help fundraise for. Suggestions?
