I play here all the time(Mostly Blackhawk--Central City as they are adjoining towns with approx 30 casinos door-to-door with each other. I sure hope I didn't contribute to this 5.1% downturn. I would feel bad. :)
The author (Charlotte Capewell) states: "...Colorado's three land-based casinos generated more than $80.8 million in assorted gross profit in January, down 5.1% compared to the previous year's $85.1 million. ..."
The casinos are in the mountains surrounded by old gold and silver mines that until recent years were mostly closed. I think all of Colorado's casinos are land based. Maybe the ones at CrippleCreek(fewest/smallest casinos & market) have a creek nearby.
