Bright and early we set out -- at Penn Station by 6:00am. That's where we had our first scare -- the Amtrak agent said we couldn't bring out bikes. Amtrak policy say's otherwise (folding bikes that fold to within a certain size are allowed at any time according to their on line regulations. We also checked by calling). The agent checked and we were allowed to board.
We then walked back to the hotel for the night.
Total milage: 1 (.5 from home to Penn Station and .5 from The Niagara Falls station to the hotel).
We did walk 2 to 3 miles though.
