Carlisle or Nats-which is better?

I always tip them. Some of those people volunteer & the tips are all they get.

How much is it worth to hang out in a men's room all day for next to nothing, keeping it clean for thousands?

They earn every tip they get.

I admit I am darn slow to tip unless it is d eserved, but I would say those guys earn every tip! I havn't been to Nats or Carlisle in years, it is so far, but I admit I refuse to pee anywhere at the Nats except the way nature intended, out in the fresh air behind someone's car!
