Last year had 100 people in line for the pre-paid. 2 people in line for pay-now. I'm doing pay now. $20 is $20 (two of us), but my time is my time - especially when I could be drinking wine. Double especially when I could be drinking @V-SHOT 's Sangria, and poking him in the eye. Precious moments like that are priceless.
I might have gotten the discount last year anyway. I will try again. Calling "Slingshot" in Clarksville is not like other places.
