You could dig one but it would be expensive or labor intensive. In the old days you could drill and blast but those days are mostly gone now.
Don't laugh, ok but I was thinking the other day that when we build the cabin we could have an outerwall stroage room that I could bring the horses in to:') I haven't been brave enough to share this idea with hubby yet.
Only toll-road contractors can drill, blast, divert, mangle..
Here you get tickets if your yard is 1" over deed restriction height or if your dog barks. Sigh.
