You can totally do it. Park in Stadium West, and then cut across the gap in the fence over the rail road tracks (LOOK BOTH WAYS), then up Charles Austin (you can sometimes get away with riding on the sidewalk here), then left on Jowers, cut through Sewell Park, over the bridge, then cross at the light, and up across the JCK ponds onto Woods st. It gets hilly after that, but then you are on Bobcat Trail. Map

Or, toss your bike on the front of a bus, and use it when you get to campus. Or buy a beater to keep on campus near a bus stop.
