<p>Around UCSD, the campus is easily walkable if you are wearing comfy shoes. Many people also ride bikes, i was there over spring break and even though there werent many people there were many bikes (on racks an such). Concerning traveling across SD, the trolley system is alright considering the size of SD, but it is fairly easy to get around some places, like its easy to go to a football game. Dont know much abut the bus system, but it is more extensive than the trolley. I dont quite understand why people dont want to hang around La Jolla, it a beautiful place with many places to hang out, the beach, shops, restaurants, parks, and many others.</p>
