I noticed a lot of roadwork in downtown Oakland today. Unfortunately I couldn't find a way into the free Convention Center parking lot. I could see some cars in there though, so perhaps there's still a way to get in there. I ended up making a big circle around the campus and parking on a meter (~$7 for the 3+ hrs).
Bart lot was full.
If anyone has information where free (or cheaper) parking is to be had please post a reply to this and let everyone know... just in case the road work isn't done by next week.
