Looking for something to do this weekend? Good news, on the first weekend of every month, Bank of America sponsors a program called Museums on Us. It admits you into any of the participating museums for free. Keep in mind, if you and your spouse or friend want to go, you both need a card to get in for free. Check out the site here and go and visit somewhere.
I've used the discount at the Please Touch Museum in Philadelphia. My daughter wasn't quite 1 yet, but she loved it. P.S. If you want to park for free, park out in front of the building, and not in the parking lot. Even if you park in the parking lot, I think it is only $5.00 or so. Which is not bad, if that is all you have to pay for. You can bring bagged lunches and eat there also.
