I've not had any serious problems entering the US, but it is always a mildly unpleasant experience with long queues, fingerprinting, and questioning by a humourless guard. The return trip is usually a little less unpleasant, with much the same queues but no fingerprinting and little questioning.

Once, when travelling from the UK to Canada, I was accosted for extra questioning because I had declared on the customs form that I was in possession of weapons. When they determined that this was a bag of swords they weren't worried and let me through, telling me that their main concern was Americans who had forgotten that they weren't allowed to bring their firearms into Canada.
