Thanks everyone for your ideas! I haven't been online all week, so I was surprised to see 3 pages! My guess is we'll probably go with the wood chips or rocks of some kind.... I'd be a little short on the $13K for turf! The ground has actually been frozen for 2 days now, so we've had a little break from the mud. Our boxers run so hard they dig up the mud when they play... none of our other dogs do that! You gotta love the spirit of boxers. There is nothing like them...
