Have probably made over 500 trips to the U.S. since the early 70's. the number is so high because of my children playing hockey in cities like Detroit, Pittsburgh, Columbus, Syracuse, Boston, Etc. 
We have not gone to the U.S. in the past couple of years because of the high exchange rate. We were thinking of visiting Southern California but relented because we wanted to see how things developed after Trump was elected. Its still too early to make a decision. 
It's actually less hassle to travel to Europe than the U.S. lately. I want to ask many of my friends who live in Florida and Arizona if there were any complications while they vacationed this winter.
