I spent my Canada Day fencing part of the yard. Our greyhound hasn't been able to run for a couple of months because we had no fenced area to let her loose. I got it finished just before supper time. We let her out, and she ran like an idiot. You should see her corner at 50 km/h! She leans into the turn at a 45 degree angle, and there are divots flying from her feet. There's nothing like the grin on the face of a greyhound running flat out!
