I purpose some zip lining on June 22 at noon. http://www.holidayvalley.com/explore-our-mountain/sky-high-adventure-park-aerial-park#.UhwIQK7D-M9
This web site about sums it all up. I figure the park and coaster for about $51 depending on how may people we get. Also I purpose that if we have ADULT family members (18 or over) let them come too because the more the merrier. My kids will want to go and they are 19 and 22. I had a blast the last year I went. Perhaps we can get a bite after.
