Hey all,
I was at Minute Maid Park on Saturday to watch my beloved Dodgers take on the Astros. I took my K-M 7D and a couple lenses, and didn't have any problem. I remember some were asking if it was ok to take a dslr and longish lens. Granted, my 70-210 isn't that big, but the security and ushers had no problem with it.
I will post some shots later (no internet connection at home right now because I am moving), but in the meantime, you can see some that my friend took here:

And I caught a foul ball too!!! woo hoo!
