So this is public knowledge now. It's still on the cusp, but there exists a high probability that a new Velodrome will be built in Lyons. Doug from Ubikes and a partner have been shopping for a while for a site to build a track. They recently pitched the idea to the town of Lyons. From what I understand, all the town has to do is donate a couple of acres and Doug and Co will take care of the rest . The Lyons town board unanimously approved Doug's proposal. It's a go from Lyons' end.
I had the opportunity to discuss this with the Mayor here. Seems that Doug and his partner looked all over Boulder County but neither the city of or the county were willing to work with them. Recently, they'd been looking at some property in Weld County. The Lyons idea works well, though, because they escape liability by buiding on municipal land - same principal as a skatepark.
Don't know how high we should get our hopes, but it could be a sweet deal.
