Yesterday I took a short 40 minute drive to the intersection of 4 grid squares, EN80, 81, 90 and 91. The intersection is in a field in back of the Pilot Truck Stop on I-71 at Ohio SR83. The EN90/91 line runs through the Pilot parking lot and the 4 corner intersection is about 400' off the pavement. The weeds and thistles were quite high and attached themselves to shoes and clothing. Other than that, it is an easy place to operate from. I made 26 qsos with 25 different stations on the two afternoon AO-27 passes. The western pass was very crowded so not many qso's.
A special QSL card has been designed and will be sent to everyone in the log. No return card necessary. You can see the design on my qrz.com page. These are not rare grids but it was my first time operating from a 4 corner intersection.
If you are looking for a change, try operating from another grid. It doesn't have to be rare for you to have fun doing it. Use Google Earth to scope out potential sites. Pack up your equipment and head out!
