Andrew G. Bennett hasn’t even graduated from Elon University yet, but he’s already a big donor. Mr. Bennett, a senior, plans to donate $50,000 to the university over the next five years.

Mr. Bennett’s gift will go to Safe Rides, a service that provides transportation to students who would otherwise walk home at night or drive after drinking. The gift will allow the program to add a van to its two sedans, and help it add staff members and improve marketing on the campus.

Mr. Bennett says he chose a cause that would allow him to reach as many students as possible.

Mr. Bennett, who has not yet decided what he will do after graduation, says he was inspired by a family friend whose parents made a donation to Elon when he graduated last year.

“For those people who’ve had a great time at college or high school,” he said, “it’s important to be involved, and give back if you can.”
