Don't have a problem paying more than the disabled and elderly.
The argument that because some disabled don't use all the facilities they should pay less is faulty from a logic POV so I'll breeze on by that point and give the author time to reflect.
I pay more to camp in some other states because I'm not a resident and don't pay to maintain their infrastructure through local taxes; makes sense to me so no reason to squawk about it.
Personally, I think its a true mark of civilization, for the younger to subsidize those on fixed incomes.
