I was starting to get into travelling to the US - but I stopped doing discretionary travel there when they started to fingerprint me.
Besides, I do actually prefer Canada to the US. But the US did make for a very easy holiday, where you didn't have to work very hard to arrange it. Sometimes it's nice just to go on holiday to slob out - other times, it's great to work a bit harder and have your boundaries pushed. Now, if I need an easy holiday, I head to Canada.. and get to explore lots of the rest of the world instead of the US. It'll still be there if ever they change their immigration policies.
