Toronto for me - appears we have quite a few here who want to go over there.
Failing that, it would be the Highlands of Scotland - exactly the reason we go up to Aviemore every 4/5 weeks for a weekend away - relax by the lochs, listen to the silence, walk the mountains, ride the bikes along a traffic free path, no smog, no neds/chavs, no worrying about parking up hoping some b* hasn't hit it.
