Interesting Travelers aka Gypsies question #1: Are there Travelers in the US or Canada, and if so, how do they differ from those of the UK?

Off of this question here, and led to a refreshing subject I did not know about. Having never thought there were still Travelers in existence, really I wondered if there were truly Travelers in other places? A while back, I watched The Riches, on FX. I figured the series was more hype than reality, so I found the documentary on the UK Travelers more credible. The Travelers in the FX series where more stereotypical of what you hear Travelers were; crooks, thieves, grifters, conmen, etc. Let see how well the Collective knows about Travelers and their differences. How do Travelers differ here in North America, if there are any, than those across the Pond?
