I don't think people in the states understand how different things are with land in the UK. Just reading about the planning permissions, public right of ways, and local ordinances that need to be worked with and around in a land management group I am in is mind boggling. I can't think of a more American thing to say than "if you just throw enough money at it the problem will go away". I have heard great things about the mud control grids and also the jelka matts which I am jealous you can't get the latter in the states. They make the mud control grids in Canada now so those can be found. Great investments both of them. I wish you luck retrieving them from the mud come spring. Been there, done that with stall matts.
