I just filled out the survey.
Earlier this week I was bitten by a dog at Ashbridges Bay. It was a small dog, barely taller than my ankle, so it didn't do any damage to my jeans much less my leg. One of these days, though, a big dog WILL bite a small child.
Increase the size of the off-leash areas if necessary, but get the off-leash dogs back on a leash and charge the owners.
