No, but if someone gives you a ride INTO a park..somone has to pay.
Read the thread a little more closely.
If you want to road walk from the bus stop to save $7, be my guest.
Most people will opt for a ride/hitch however and someone will have to pay the entrance fee.
That someone may not be the CT hiker..but if I was to get a hitch from someone, I'd volunteer to pay the entrance fee.
