a) The restroom, or toilet

I was late for my meeting, but I had to make a stop over at the chamber of commerce before my bowels let loose.

Chamber of Commerce Weather 

Any type of sunny weather that would attract visitors to your city. In Atlanta, that means 65 degrees and sunny on a Saturday in February.

We had a client team come in from Detroit on Friday, and due to the Chamber of Commerce weather, they just wanted to go to Park Tavern and drink all afternoon.

Chamber of Commerce Day

Traditionally it has meant a day with gorgeous weather that would encourage tourists to visit and companies to relocate to a particular area. In Atlanta, it means a mid-October Saturday when it is 65 degrees, not a cloud in the sky, and you are out drinking on a patio with a woman who has no problem going down on you after your second date...

"Hey, it looks like a Chamber of Commerce Day this Saturday; 70 degrees, light breeze, no chance of rain, what would you say to the Treehouse for a late liquid lunch?"
