Did you guess the Tech-Ed theme yet?
When I first arrived, I thought it was "finger painting", because of the logo.
But now, after spending a week here, I realise that it's "Weight Management".
Interesting sessions are frequently posted on one, then the other, side of the building, with no way to go but down the stairs (or escalators, when they're working), across the length of the main hall and expo floor, then back up the next set of stairs.
Finally, today's lunch (the last lunch at Tech-Ed is always pretty poor food) ran out. Completely expired, with hundreds of starving techies waiting to eat.
Not a pretty sight.
When food finally did come, it was "fried vegetables in a bun".
Now, granted, some of us might need to lose the weight...
