How much would it cost to build a mega shed somewhere for the purpose of housing an all weather indoor Mountain bike track? If you were clever you could design trails to change routes (like train tracks) to go from being a low tech XC run to a more challenging one??? Think big, like Woolworths warehouse big! Also think of Golden Jubes, but undercover. You could keep the greenies happy by collecting all the rain water! And we'd lighten the load on wet trails...
Yes i know, the rain is driving me crazy! But if this was Dubai....
