Summer jobs/volunteer in Houston for school teacher.

I’m a teacher who moved to Houston at the start of the school year. I’m wanting to work during the summer months and weekends next school year. What would be some good jobs around Houston that are seasonal? I really want to be a bar back/bartender but I’m open to other jobs too. I wouldn’t mind volunteering either I just want to meet other people preferably my age (mid 20’s). I’ve worked a lot of odd jobs in my day so I have experience in a lot of things.
