If you do land on a little used public road, there is a good chance that it will become clogged with traffic as everyone wants to see the plane on the road.....
That happened to me near Mt Taylor. Doing fire patrol, the spotter with me needed to pee so I landed on the road and pulled into a scenic overview. And then every car and RV pulled up to see what was wrong. I had to send people out to block the road so we could take off. We never got a chance to pee.....
I once landed my glider in a field right beside the highway. At the corner of the field was a convenience store. So I let my crew, who was flying another glider, know I was down ok and would wait for them to come get me.
So walked over to the convenience store and bought a sandwich and a pop and went back to the airplane and sat down under the wing to eat my sandwich. Every few minutes someone would stop and ask if I was ok or needed anything.
After about 30 minutes a Green Chevy pickup rolled up with the Gumball flashing in the windshield. An Officer got out and asked “Are you the Pilot”, “Is any one hurt”. At that point he stepped back to his pickup and called on the Radio “You can cancel the Fire Truck and Ambulance”. He explained someone had called 911 and said an ultralight had crashed in a field.
We talked for a couple minutes as I explained I was just eating my sandwich, and waiting for my crew to arrive. While it had been an unplanned/forced landing, as I would have preferred to land at the airport, the landing itself was perfectly normal. I told him I could help since the wings come off the glider, I could remove them and lay them out in around the airplane and make it looked more like a crash site.
Then the Firetruck and the Ambulance showed up, since they had almost been there when the call was cancelled, they wanted to see what was going on, even if they weren’t needed. So I got to explain to them again that I was just eating a sandwich while waiting for my crew. After talking about gliders and soaring for a bit, they left and I finished my sandwich just about the time my crew arrived.
While I have landed in fields a number of times since then I haven’t landed near a major highway, however next time I do I will probably call 911 and let them know I am there and I don’t need emergency assistance, since every 3rd person with a cell phone will probably be calling in a plane crash.
