"A U.S. visitor should receive fair exchange for his money. When he realizes how much further his U.S. dollars go in Canada, he might spend more of them."

That quote is from a little brochure published for Canadians by the Canadian Government Office of Tourism. The heading reads, "Tourism is important to all of us," and goes on to point out that the industry is "one of Canada's largest employers. More than one million jobs depend on it!" It advises readers to "Reach out a friendly hand. Isn't that what you want when you're away from home?"

I must confess that I am slightly prejudiced about Canada, and also that I feel a little guilty. Let me hasten to explain that the guilt concerns pollutants being emitted primarily from U.S. utility and industrial plants that are causing acid rain that threatens animal and plant life in lakes in eastern Canada had the northeastern United States; the prejudice involves a warm feeling that grew red hot after the Canadians risked Indian wrath to rescue some of our diplomatic personnel when our other friends were merely wringing their hands.

Mature travelers generally do not make vacation plans on the basis of whether they like the government of the country they plan to visit. That's most fortunate for the tourism industry. If we began crossing destinations off our lists solely because of displeasing political factors, there would soon be a lot of empty hotel rooms -- though there have been a few travel "boycotts" by Americans in the past in an effort to penalize by withholding dollars.

Most American tourists, realizing they are living in an imperfect world that does not resemble Camelot, no longer expect to be loved by all foreigners, as we have commented before . But they do expect to get fair treatment and be reasonably safe.

Tourism is spoken of not merely in crassly commercial words but in terms of "peace and friendship" -- at least among peoples if not governments. And Americans have learned that peace and frienship have never been a one-way street with Canada. The border is open, conditions are excellent, the welcome is genuine, the dollar goes further, and there's much to enjoy. Ask your travel agent.
