To those of you that use Trapster, how do you have your warning distances set? I recently have mine set to alert when I'm within 500 yards of the particular spot but the distance seems to be quite a bit off. I'm making a trip from Kentucky to Alabama tomorrow so I'd like to get this little situation figured out tonight. I have a Tomtom btw. Like I said, some of the distances were off when I used it before. I was within 50 yards of a couple of spots before the GPS alerted but on other points it seemed to work fine. Do yall think it'd be safer to set it to about 3/4 of a mile or so to ensure it alerts at a reasonable time?
