here's a free one... Maymont park in Richmond. It's a killer place to go for the day and have a picnic or something. They have all of these different types of gardens that are really old and cool as hell.
It's a kick ass place to take photographs if you're into that kind of thing. I would go about once a month to check out all the different gardens because they'd all look different every time you went. They also have a petting zoo!
It sounds gay, but I had some of great days there back in the day. Just a thought.
