I don't think it will increase the traffic on 285. I don't have any numbers, but I'd bet that the people coming up from the flatlands will just consider the park another stop on their trip 'to the mountains'. I can't see it attracting any more than already come up, it doesn't offer anything that's not already available in other parks along 285.
We'll see on Friday whether the boat and RV show gets worse or stays about the same.
