What's a lock in???
OK, well.. at one point or another none of us knew what a lock-in was either, so....
It's just what's it's called. It is a fun night of activities where you are locked-in a certain place and not able to leave. (see where that name comes from now?)
I did this a couple times in HS, and it was at the school's gym. We partied all night long *to the surprise of some of the teachers who had caught us dozing off in their classes that day(was on a Friday), and we didn't leave till that next morning.
Guys slept in the hallway, and the girls slept in the dance studio section.
(Well, that is if you actually did go to sleep.. lol)
Our team's lock-in is usually the same deal, but movies and games are played all night long. Last year we had a pool at our disposal to use, but I guess it is being renovated this year, so no pool for us.
It's a good team building exercise, or just a fun time.
