Last time I was car camping I felt lucky to happen to have a large piece of disposable plastic used to protect car trunks from mulch or potting soil that Lowe's (home improvement store) gives out. I was able to put it on top of the poison ivy sprigs that were under my hammock and throw it away later. Then I topped that with the bath mats that I use to help load my kayak on my car.
I am a car camper, so weight is not an issue. I'd never make it trying to hike and carry a dutch oven LOL. I use a yoga mat. It is pretty water resistant. It's long enough to set gear on if I want. I can use it to sit on, and I can use it in my hammock to add some insulation if need be. It's also washable for when we have our wonderful pollen season. I can even roll it up and use it like a bolster.
If you don't like my cooking there's always MRE's.***Hotlips
I made a Tyvek ground tarp as well. Sewed a simple hem on all four edges with 4 corner tie outs of grosgrain. It's about 3 x 4 and weighs nothing.
+1 for Tyvek. Thanks fedex.....
++ on the Tyvek. Bought a couple pieces on EBay.
Count me in as one that doesn't use a ground cloth. I did buy a piece of Tyvek from AHE and it's in my pack but I likely won't use it. Pretty easy to just take the boots off sitting in the hammock.
I go barefoot so i dont have need for anything tostep tobeside the ground. It works in winters also
