I went to summer camp for adults and it was like a frat party on steroids

More than one million adults attend camp each year, looking to relive their childhood memories or experience a summertime tradition for the first time.

While kids' camp attendance has declined in recent years, forcing many organizations to close their cabins and sell off their land, the number of camps for adults has swelled faster than a mosquito bite, according to Grownupcamps.com. There's a camp for every type, from Camp Rosé All Day to the more traditional Camp No Counselors, which appeared on "Shark Tank."

And when campfire s'mores and sing-alongs are mixed with "flip cup" tournaments and a bunch of singles cavorting to DJ music, the result is a rowdy sleepaway camp experience unlike the one you may remember from childhood. In 2014, at the onset of the summer camp for adults boom, I attended Club Getaway in Kent, Connecticut, to see what the buzz is about.
