OK To do this right you have to bring a blanket,(or low lawn chairs if you prefer but you have to sit farther away so other people can see) a pillow some wine, cheese and crackers. Get there early for a good seat! That is key. If you have kids there is a little playground nearby..take the kids there early and get them pooped for the show. Have fun! ps donations are welcome!
Pros: free, educational, relaxing
Cons: weather dependant
