Open Question: What is their to do other than camping?

Well, my friends any i are thinking about doing something for graduation. We were thinking about camping and staying over night, so we could hang and have one of our last hang out sessions before college. But we are trying to find different things to do other than camping that have to do with staying over the night. In other words we don't want to be at our houses. Can any of you help me by giving me suggestions on other things to do? Oh Btw were in Houston TX.
