WINDY WEIGHTS
Upon arriving in a campground, I used to ask the kids to find some rocks for me to use to hold down our patio mat. 
Unfortunately, the rocks were usually dirty and would end up getting kicked or tripped over. While walking down the sporting goods aisle of our local department store, I noticed that it sold individual weight rings for bodybuiling. Problem solved. I bought six 5-pound weights for less than $3 each, and now carry them in my RV’s basement storage. Now, when we arrive at a campground, I just place them around the mat. No more searching for rocks, pounding of stakes or stubbed toes.
