Out here in CO, one reason for the crowds last year was the lousy (for us in the US) dollar exchange rate, which brought the Europeans across the pond by the maze-full.
Usually we can get super-cheap last-minute lodging deals in Jan. and Feb in Vail or Avon, those were very hard to find last year. The bountiful snow contributed to our overall crowding, too.
Our recent mid Sept. storm pasted the peaks with a nice dusting of snow, prompting the Vail maketing guys to send out spams of "we've got SNOW!" which is already long since melted, but may have gotten the bookings going.
The shaky economy, and slightly better exchange rate maybe will put a damper on the crowds, but I sure wouldn't mind skiing another epic season just like the last one.
I got to ski Vail twice last year when the Front-Rangers were trapped on the wrong side of the hill due to Vail Pass closures, and it was still quite busy with the Euro ski-weekers stomping down the back-bowl powder at an astonishing rate.
(Also got diverted one morning from Vail to Snowmass due to a Glenwood Canyon closure, which sucked only because at the end of the season I left one Vail ticket on the table, and had to buy and extra 'Mass ticket- wah.... :-({|= )
Anyhow, I'm not too excited at payin' $4 per gallon to get my SUV the 300 miles RT to Vail this winter- but I'm not planning on leaving any of my 10 Vail/BC ski days unused this year, either.
