Girl, you are crackuppin' me! It reminds me of my college summers as a rec director; rain? unmbrella hike and puddle jumping! too hot? pool games! too pruny from the pool, scavenger hunt! Heh, I averaged 12 miles a day in them woods. I digress.
I used to go on murder mystery train trips and my friends and I got really into it. That could be a fun thing to try, but it's a lot of work and writing. We could call it something fun like, "Online Flatline".
We could do a kind of 20 questions thing, I reckon.
Okay, you make the game, KD, and I'll play.
