Two ways to see a tourist attraction

On TRINET there had been a discussion on metropolitan areas that overlap multiple countries.  Someone posted this wikipedia page for a fairly comprehensive list:

I have been to a few of them, most notably Niagara Falls.

China to accept US Credit Cards

China has announced that foreign companies like Visa, MasterCard, and American Express can bring their payment processing operation in that country starting 1 June 2015.  Should be a boom for tourism!

Fall tourism in Northeast?

Getting ready for my Saturday morning errands that includes listening to Car Talk, and I caught this news on WAMC website.  The article describes the anticipated traffic across the US and Canada border.  It reminds me of a casual conversation with someone it a store this week that raised the concern for the need of passports for her family to cross into Canada.  Four passports, the time and cost to acquire them was seen to be a deterrent to local cross border tourism.

While the exchange rate is still comparable between the US and Canada with $1.00 Canada equal $0.949 US, I wonder how much tourism is list due to the Passport requirement?

It would be a good thesis.
