poor (and crippled!)

So, I wanted to do something fun (and get out of my college town) and cheap this weekend. it wasn't going to be too difficult..

except my friend sprained her foot last saturday so that rules our hiking/camping plan (and i'm thinking most outdoorsy things, she's on crutches!)

So....what can we do for fun that doesn't involve a lot of walking?

I'm thinking we'd have to scratch the whole trip idea and instead do one or two day trips somewhere..

we're in the sacramento area.

Thanks!
Fishing or doing a gentle boat trip (raft, canoe, or kayaks) should still be fine, if either of those are options for you. I'm not feeling creative enough to come up with much else, esp stuff that doesn't cost much money. :/
