I flew a 172 off a road when one of our renters ran out of fuel about 6 miles short of the airport. No big deal, and I don't think I deserved a medal or anything.
The Ag applicators operated from gravel grid roads in my area for decades and aside from rolling a few into the ditch and writing off the airplane out of thousands of operations, nothing unusual for those guys..... part of doing business.
Its about selecting the right spot at the right time with the right aircraft, not a blanket yes or no to landing on roads.
