Dear folks, This is from Oklahoma. I spoke with you on the phone on Wednesday, ordering some new liners for our 18’ers and 20’ers. This will be our 3rd summer season with a Shelter Systems tent camp. So far, we have nine tents, a mixture of 20’ers, 18’ers, 14’ers, 8’ers, living & greenhouse tents. Even our seven cats have their own tent! Thursday, the day after we called you for the liners, we had a storm come through. We’d set up several tents, but had not staked all of them down. Okay, that was stupid, but it did have amusing results. Three of the tents took off rolling, one making it through a grove of trees, over a low concrete wall and out across the south pasture. There was a little tearing of this three-year-old tent at one junction (actually, that may have already been there), and one pole fell out. We picked it up, moved it back to the site, and (finally) staked it down well. Of all three tumbling tents, one lost a pole, and another had a window pole snap. Can’t help admiring how durable these things are. They even stand up to our sins of omission in properly tying them down!
