Awesome fried chicken
There's a great fried chicken take-out place in Damascus, MD called Red Rooster.
It's pretty easy to get to, just take Rt. 27 South from I-70. You can use I-270 as well if you're coming from D.C., but I think it's a tad closer to 70.

It's kind of easy to miss when you're driving on 27; it's right behind a gas station. Keep a look out for this sign:

The building is quite small, and the lobby where you order is even smaller.

The lady who runs the place is called "Miss Pam" by the high school students who work there. They seem to like her a lot. She's quite a character.
The chicken is awesome, and I highly recommend the slaw and onion rings as well.
