We used these last year at Gooseberry State Park in Two Harbors, MN which is along the shore of Lake Superior. Our site was smaller so we had to put the screen tent on the gravel parking pad, and the site where our family tent was also rocky. I couldn't believe how well these stakes performed, so I had to order another four pack. I've used a lot of different stakes and I have a large box of various kinds of tent stakes I no longer use. These stakes along with the Galvanized Steel Hook Stakes from Campmor are the two types of stakes I carry in my stake sack so I'm prepared for all types of soil conditions.
