The Centennial State has been trying to go to Permanent DST for years and years, all with little success. Why?
It turns out the ski industry is against it.
When a bill was heard in front of the Colorado Legislature and I went to testify in favor. The ski industry was there to voice opposition, but the only reason the lobbyist gave publicly was that the operators needed the morning sunlight to examine the ski lifts.
I suggested we all pitch in and buy them some flashlights. :-}
In spite of what I thought was a very helpful suggestion, the bill still died.
I found out later that my theory of why the ski industry is against permanent DST is the actual reason: Once a ski area has sold you a lift ticket, it does not make any more money off you unless you stop skiing and get into a bar or resteraunt. If it is light, later, you just ski more and then you might even just go home rather than go aprés ski in an establishment at the ski resort.
So, that is why bill after bill has died here in my home state of Colorado. The ski industry has very very good lobbyists.
But here in 2020, an intrepid public servant, Ray Scott, is trying again. Click on Colorado below to see the latest with that bill.
Update. It didn't go well.
