I did it back in college too. We had a great club that really catered to students. It was $ 14 for a 2000 ft tow, and $99/yr for a membership, that included all glider rental for the lower performance ships (Schweizers). The instructors were volunteers, but you had to wait. There was a signup sheet, and the first one to get to the field got the first flight.

Weight wise I was skinny back then and it wasn’t a problem. I soloed my first full year and got my license the next year.
