The sign says "Trucks Only Rest Area".....funny thing is that most auto motorists don't read signs and pull in here by mistake. You, who are infinitely more intelligent, can fake ignorance, and stop. The cache is a little more than a PNG that is just off the Indiana Tollroad, I don't know if it is accessable from the local road or not, since I can't drive my tractor-trailer down the lane to find out, and my schedule prohibits me from taking adventures of unknown duration. This should be another quick smiley for those of us that are travelling the highways and byways.
