We always joked that his method of play was to think "Can I break it?" and I thought he would grow out of it, but no it seems not. Everywhere we go he has to test everything to the limit. He obviously has lots of energy he needs to burn but even when I take him places he can run a bit wild he always ends up going too wild and I have to step in before he hurts someone or damages property. I'd love to let him loose in a scrap yard and say "Go for it" but obviously that's not going to happen.
