The time stamp on the press release reads 4:13 Eastern. There were a few August 4th guesses and a couple of those were very close to the right time. The winner is EthanDR. He guessed 4:01 (ish), so just off by 12 minutes.
Ethan, if you will email me your address, I'll send you out your prize. Well, actually I will send it out August 16, as I'm off to Vegas next Monday and will pickup something with the 51's logo on while there and mail it when I'm back. Don't get too excited, I'm cheap.
I get to see 3 games of the Brett Lawrieless 51's, then have a couple of days in Vegas to lose at the tables.
Congratulations Ethan. Great guess.
