Driving thru George Washington Bridge from NJ is costly - $8. If you do carpool (3 people or more), it's $2. So to save money, I stop by at this bus stop right before GWB and pick up 2 strangers.
Sometimes while I wait for bus at that same bus stop, some stranger came by and asked me to hop in. I pay nothing. Bus fare is $1.50. NJ Transit w/ disability discount = 75 cents.
