I've been to a couple of them, no big deal.. A couple of the guys that I go on a football trip on each year are Cowboy fans. The worst one I saw there is detailed here from the Washington Post:

Nov. 16, 1997
At Texas Stadium
L, 17-14
The Redskins were in total control for the first 55 minutes of a game they absolutely had to win when the Cowboys jump-started another miraculous comeback. With Dallas backed up on their 3-yard line with 5:48 left, quarterback Troy Aikman engineered a 97-yard touchdown drive, plus a two-point conversion, to pull the Cowboys even at 14-14. A devastating three-and-out on the Redskins' next possession precipitated a dismal 28-yard punt by Matt Turk, which gave the Cowboys prime field position. Twenty-eight yards later, Richie Cunningham booted a 42-yard field goal with four seconds remaining to give the Cowboys another unlikely win. The loss was symbolic of the maddening disasters that befell the Redskins during the Norv Turner era, and they would finish out of the playoffs once again that season.
