Actually, we don't run as much as the players do. We run half the court. Most players run the entire court. We make half as many trips as they do.

I do drink water at half time. But I've honestly never been so thirsty that I couldn't wait until then or until after the game to do it.

On game days...
 

and other days as well, I drink a couple gallons. I buy one of those Aquafina bottles, and keep filling it up at work all day.
I make lots of trips to the bathroom, but I am SUPER hydrated for games. I never bring water to the table. I really do not think that it looks all that professional.
However, some schools up yonder here, have student managers bring a towel and a dixie cup of H2O during time outs and at quarter breaks when we are at our marks.
Nice gesture.

Hey Chuck!
First Feild Lax game since the xmas break. Mild winter here, no snow this season. Western Canada, British Columbia just east of the city, Vancouver. Vancouver, and the ski resort Whistler are putting a bid in, to host the 2010 winter olympics.
