I've got a day coming up in Cambridge. I'll be on my own so things like punting are probably out! I like walking, seeing unusual things off the beaten track and museums. Not as keen on art. Was thinking of doing my own walking tour, but wondered if anyone had must see things as I go around. Wouldn't mind a peek in a college or two. Also some nice places to eat which are welcoming for the solo traveller would be great. Thanks!
