Anyone familiar with how they count cars using those long wires across the = road? I'm wondering how accurate it can be. Eg. Two lanes and two cars s= ide by side hit the wire at the same time. Does it count 2 or 1? And a tr= uck with a boat trailer with 2 axels on the boat trailer, does it count as= 1 or 2? An 18 wheeler, does it count as 1 or 2? A dually, does it count = as 1 or 2? Seems like a lot of factors they can't count on... And speakin= g of which, say some idiot is riding your bumper, does him and you get coun= ted as one small 18 wheeler, or 2 cars? -- KF5QEO John Guillory westlakegeek@yahoo.com Cell: 601-754-9233 Pinger: 337-240-7890 Google Voice: 601-265-1307 > On Jul 8, 2014, at 1:11 PM, William Bross wrote: >=20 > Have you looked at Open Office Draw.
