I'd have to say 5 days on Cataract Canyon at high water. 40 people with 110 cases of beer, 20 cases of booze, 3 guitars, a fiddle, and more illegal fun than you can shake a stick at.
Pulling into the new Hite at midnight, absolutely out of our minds on various fungi, in the middle of a raging storm replete with sand stakes pulling and getting flushed into the lake.
Not exactly the most intimate trip, but what a rager! Also not the best way to introduce a newbie shy girlfriend to the river scene.
That pretty much defines the Cockroaches.
