Welcome and I do get groceries, got some today but I took the back trails down the pipe/power line because the road was closed for repairs I came out midway on the stretch that was closed right across from the road that turns to my place. The guys on the backhoe crew stopped and looked like, where did he come from.
So it's ok to haul food!
You could go by way of Bolivar Peninsula for an adventure in procurement!
Watch out for buried land mines, give getting groceries a whole new meaning.
