As a resident of Vail for the 20 years this project has been discussed, my opinion is build it where there is the least opposition to it. There will always be NIMBYs (Not In MY Back Yard) in opposition to any issue.
But build it now! It is long overdue. Don’t spend any more money “studying the issue.” Just get it done! If we (the residents of Vail) had all the tax money wasted studying the issues in my 26 years here, we’d have more parking, parks, nine-hole golf courses, local housing, etc., among other things. And a lot less tax money wasted over the years.
