No, no and no.
Parking is difficult. Get your name on the list and see if you can (eventually) get into the town lots (B, D and G I believe). they are the cheapest, but it took me 16 months to get in myself.
Aside from that, there are garages all over, but they all cost upwards of $225 a month. The only thnig I can say is use the phone book orgo for a walk and start asking around.
If a place is too far for you to walk to, most likely you would not want it for a daily commute anyway.
Sorry I did not give you many specifics, but to give you an idea, I have been in the same garage for about 7 years now even though it is almost a mile walk to it. For $175 a month, I am not ready to give it up just yet...
