swadiver is right, something between you and the astorturf is recommended. A lot of us use a cheap cargo mat they sell at Harbor Freight, which is very reasonably priced. Might be a cheap and quick solution for you that you can usually find at any local Harbor Freight. Here's the link: https://www.harborfreight.com/72-in-x-80-in-camouflage-utility-cover-69508.htmlit is astroturf, but a mat is more comfortable
Looking forward to seeing you at the February monthly match!
