If you're still in the area, I'd suggest a brief stop at the Kemah Boardwalk. The Boardwalk Bullet wooden coaster was a lot of fun when I rode it last month. (FWIW: I rode it at night and after a light rain and had some great rides on it.) If you fancy more Saltgrass, there's one at the Kemah Boardwalk (along with a bunch of other restaurants).

That Kickback Cafe looks awesome! (However, did I see some insert-wear on that floor!?!)

Other (amusement parks) suggestions while you're in PA:

Hit Kennywood since it's RIGHT there in Pittsburgh!

If you have time, Hershey Park (a bit East of Pittsburgh) is one of the best (IMHO) amusement parks here in the States! Riding the back-row/outside seat on Skyrush is one of the most F-ing INSANE experiences ever! Rider Beware!!!!!

Then there's Knoebels!?!?! Pronounced "KA-NO-Bulls". I grew up in Orlando, FL and I've traveled extensively in the USA (and even some places abroad), but Knoebels will always be my favorite amusement park in the States! From the "lovely hillside setting", to the free parking, free admission, cheap (but delicious) eats, along with one of the BEST wooden coasters in the world (Phoenix), (heck...did I even mention the pinball machines?!)
