We thought our holidays were one of a kind, LOL
Like you it consisted of, loud obnoxious children destroying trees etc. With no concern from their parents. Dogs being left tied up alone and barking for hours.
The worst offence that we experienced, that can have you permantly banned from a provincial park... People left their fire, burning well with large flames. They left for an hour and when they returned it was still showing unburned wood. It was huge. We did not leave our site because we felt someone needed to keep an eye on it. We informed the warden...they were gone when we woke the next morning.
No wonder our provincial parks are closing a lot of parks. The abuse and lack of respect people have for where they are and other campers is outragious
