Worst US/Canadian border crossing

Just crossed into Canada last week at Niagara Falls. Handed the agent our passports and he asked where we were from and where we were headed and why across Canada. Told the agent it was a shorter trip from Niagara Falls to Chicago if we went across and through Michigan. We were waved through and on our way. Years ago I used to fly into Canada for work and the customs agents in the airport were much worse. I sat there once for three hours while they did something in the office. Never figured out why I was held for that time but they eventually let me into Canada.
