Thank you to all who have expressed your support, offered to help (and voiced your frustration). In this day and age I sometimes feel a devotion to the truth is viewed as a character flaw. If I ever am motivated to conduct another study of the type I did in 2004, I will do so in compliance with the applicable regulations. With the help of a few other volunteers a very accurate study could be conducted. I would propose a protocol of asking vehicles to stop at a point near the boardwalk parking area to give number of occupants and zip code, The vehicle could then be given a non permanent sticker to prevent double counting. Easy enough and very accurate. One wonders why this is not the standard method for sanctioned studies?
