Things to do in Cambridge when you're dead

[j4]

Anybody have any suggestions for interesting things to do in Cambridge on one's own at a weekend? Preferably things which are cheap, and absorbing enough to take my mind off other things.

find an O/S map.. drive someplace south of cambridge that seems to have lots of paths/white roads/streams.. go for a walk. (with camera for streams/churches) [south of cambridge because then you won't be able to see the entire walk from the starting point]

we've had nice walks from bartlow, hadstock, ashdon and castle camps.
