people don't come to the show to move to denver, although a boost for the housing market couldn't hurt right now. people will come here to look at the new stuff and then go back to their homes/shops in other states. when they come they have to stay in hotels, go out to eat, rent cars, and buy souvenirs for their peeps back home. this is where all of the $30 mill in revenue will come from. tourism keeps our taxes low. the likelihood of anyone going skiing during the actual show is non-existent because, duh, they'll be at the show. and if the open and the x-games continue the trend of overlapping with sia, then people will drive I-70 anyway to get there, regardless if the show is in denver or vegas. traffic already sucks on the weekends, as do the lift lines but they're not going to go away or get that much worse because sia is in denver. only about 20,000 people attend sia which is nothing compared to the 26.9 million people that visited colorado last year.
and you can go to and enjoy the vegas show if you're not over 21. it's just not as fun at night. and we have open container laws here.
