Honorable mention goes to Eckie's Pond. (Guess that makes me an old timer.)
And a shout out to the Fraternity House, whenever I could convince some girl that it was safe. (...Although most of those nights were interrupted by some smartass busting in on us through my window, or setting off a fire extinguisher under my door.)
Bonus points go to my then-girlfriend for sneaking me into the KD House on a few occasions. Always had to be up and out before sunrise, before the house mom started making rounds.
Damn, good times.
