Updated Original Post:
There is an opportunity for a zip-line adventure about 70 minutes away in Louisville, KY. This is NOT a planned cruise or adventure, however it could be added on to the end of the Mega Tour that is planned for Friday, or done on your own at another time if you wish (They are open on Sunday if you want to go down after our breakfast).

There is also a Groupon available for anyone who has a group of 4 or more that want to go.
It looks like an absolute blast, but unfortunately doesn't fit in with the events we already have scheduled. I apologize for not getting this in the original event ideas, it totally slipped my mind that it was nearby!
