Sometimes we just grab our tent's ground cloth, get clear of the bike, and try to stay dry, until it blows over.
This was 10:00 in the morning while touring in The Netherlands, and this is actually how dark it got. This is a picture with the camera's flash on. It was really spooky. We were digging out our raingear, and the groundcloth. It was one hell of a show for about 15 minutes
We had just set up our tent in a small RV park in eastern Oregon when the pre- frontal squall hit. The winds caused a wildfire to jump the highway closing the road, and was strong enough to blow down these large cottonwood trees. Our tent was fine; we pitched it behind a pretty stout fence.
We couldn't out run this one so I'm digging the ground cloth out. We laid the bikes down and got about 20 yards away in the roadside ditch. We were the tallest things out there (southern Idaho)
