I really want to put sand down in my run so that I don't get as many muddy eggs this spring when we go through mud season. I know that the best price will be if I get a truck load from a local construction or landscape business rather than buying the bagged stuff at the store. But I'm not sure what to search to find sand by the truckload. I've tried doing internet searches for construction sand, sand, and aggrigate and haven't found anything promising as far as a local business. Would I be better off looking them up in the phone book and just calling the local places for prices? Or is there something else I could type in to the internet search/online yellowpages that would give me some leads? Also, does anyone have any handy formulas or general guidelines to help me figure out how much sand I will need? How deep should it be?
