I don't know what to tell you to use in the turn outs?? I do know that it takes a lot of gravel, stone dust or whatever if your putting it on bare ground for the first time, first you need a base or it will all just soak into the ground.
I bought fly predators this year but the flies are still bad and they keep biting me as I'm painting causing me to slap at myself with my wet paint hands. I'm going to put the kids to work hanging fly strips tomorrow.
Just got in, showered and ate a bbq chicken sandwich, chips and French onion dip should not have eaten this late but I was starving!!!!
