Are you, or is someone you know coming to TAMUG this summer/fall?
Folks do ride their bikes around campus some... occasionally people go for rides down to the far end of Pelican Island. If you (a student), or a friend have a truck to take your bikes to the seawall, there is plenty of riding to do there.
I know several people without cars. There are usually plenty of people who are willing to give rides to and from the main island or even the mainland. It works like this, tell your roommate and suite mates and a few other people that you need to go to the grocery store/wal-mart and by the end of the week someone will be take you.
There is also Island Transit. Which is local, public transportation. As I understand it, they make a couple of trips a day to and from campus.
It certainly can be done.
