I'd go back. Ideally about 2,000 years so I could see brochs in use, or about 5,000 years so I could see our stone circles being built and used.
1,000 years would stick me into the Norse era here. That'd be interesting, and there'd probably be a lot more Pictish stuff around for me to look at than there is these days. A couple of brochs may still have been in use too. They'd certainly be in better condition than these days. I'm just thinking out loud now, so I'll stop.
