Anybody going to the Philly Show this weekend?

Was thinking about attending the Philly show this weekend, but have never been to a decent size card show. Would it be worth the drive if I'm looking for primarily McGwire cards from 1997-2001? And do any/some all dealers there take credit cards, or do you have to carry around a mob roll?

As far as strategy, some feel that Friday is a day for deals as some dealers want to get some money back in their pocket right away to offset show costs (tables fees, hotel, flights in some cases, etc...), and others feel that waiting until Sunday works better as you may catch some dealers that havent had the best show and need to make some money back before it's over. I just happen to be going on the Saturday because it works into my weekend schedule better.
Sounds like that could be an exciting weekend , I had no plans to do anything , maybe I'll take the old lady and the boy .
I'd really like to pick up some bats .
Does anyone know the address ?
It is definitely worth attending though, as there is a ton of stuff there you will not see in person regularly.
