Well, we had the gravel around an old play-set which we sold and spread some of it around the horse area. I believe its something like 18 yards or so for 2" deep in a 20x100 area. 2" is not going to do much, but since there is about 18" of road base under that (with a bit of dirt on top) it will hopefully be good enough for my horsies.
About how many inches of mud do you normally get? It is recommended to get enough gravel as mud plus one or two additional inches. If you get 3 inches of mud, you would want 4-5 inches of gravel. It is a good idea to put down textile fabric stuff to prevent the gravel from being ground into the dirt. I have heard of rock salt being spread across horse arenas and paddocks to help bring down dust, but I have never tried it. Unless you have very little mud in a poorly drained area, you will want to have footing and good drainage. Also, don't use any wood products that could decompose like wood chips, shavings, or straw as they will just turn into more mud.
Edit- yes, woven wire makes an excellent horse fence, as long as the holes are 2x4" or smaller. If they are any larger a horse could get his hoof stuck in the fence. Horses love to itch their butts on the no climb so it is a good idea to put up an electric strand in front of the fence. With no climb, you can use t-posts which are cheaper and easier to install than the wooden posts, but it is a good idea to put wood posts up around the high stress areas (corners, water troughs, etc.).
