Almost dying...
Jumping in a boat with my wife and 2 friends to avoid dealing with police over some BS fight between some people while at a party on a lake with only one way out... the road the police had blocked off.
Long story short... a few hours later cruising back to the spot the party was at to catch a ride. The boat sank within 5 seconds. Me, my wife and 2 friends all in the middle of the lake in the dark with the life jackets trapped with the sunken motor boat.
A 45 minute swim to shore not thinking someone is going to make it... it just sucked.
