I have another perspective. I have a short term rental home in Pinetop where rental business has also dropped off. My measures of tourist volume are different for the two places. In Pinetop I'm measuring rental vacancies; I don't know if tourism there is actually down since the supply of Pinetop rentals could simply be too high for the market. For Rocky Point, we're measuring cars going through the border on weekends when the volume should be higher. Neither approach is a very scientific, but assuming seasonally adjusted volume is down in both places, maybe there's a common cause. Gas prices? Inflation especially at restaurants? Or are we seeing changes in public preferences for how to spend vacations?
Maybe it's just a coincidence and the business declines in both places are caused by forces unique to each place, but I have to wonder.
