Visits to Yellowstone National Park last month slipped slightly according to the monthly report from the National Park Service Public Use Statistics Office. That report says 27-thousand-752 people entered the park for recreation – a 1.5% decline from last year and another 44-thousand-319 were in the park for non-recreational reasons – a ¼% increase in business. Together, the total traffic into the park spells a decrease of less that ½%. Grand Teton saw a much higher decline according to the report, but park officials quickly point out that technical problems with the counters make the statistics very unreliable. Those published statistics show a 35% decrease in traffic into the park.
