Clue 9 = Pina Colada.

I have a second correct answer from the last clue. You can do it.

Clue 10 = June 11-12, 1962.

This ends the third thread. Not sure where else to go after this one.

Last clue

Giving you an address to figure out.

2801 _____________ Avenue
_____________, WV

The first space is who always saved Nell from Snidely. (just the first name)
The second space is the home of the Big Reds, Patriots, and Crusaders.

Mystery Postal #304 is now closed!

The correct answer is An Escape Room.

Clues:
1. It is a timed event
2. 45-60 minutes typically in play to solve the clues and escape the room
3. Teams participate. It is an interesting team building experience. Our group was 8 with a 9 month old (yes the infant from the Mountaineer picture) along for the ride.
5 - It take clues to solve
4,6,7 - Intimacy Acceleration is a Big Bang episode in which the group goes to an escape room.
8, 9, 10 - All had the theme of escape: Steve McQueen The Great Escape, Pina Colada (Escape song), June 11-12, 1962 Escape from Alcatraz
Clue 11 was the address of The Escape Room in Parkersburg, WV. If you didn't get it Dudley Do Right is the one who always saved Nell from Snidely Whiplash.

Promise to make 305 easier and more straight forward.

I enjoyed this one. Once you put everything in there, I now understand it...every time I typed on Piña Colada, escape kept popping up in the search. =)
