IMO trails like Wildwood will never be opened to bikes. People simply don't want to share the trails. Groups like Friends of Forest Park are primarily comprised of people who do not ride mtb's and hide behind 'erosion concerns' or 'wildlife impact' as legitimate sounding reasons why mtb's should not be allowed on ST in FP. (don't get me wrong, if these are legitimate concerns, they need to be addressed before building a new trail). From my perspective they just don't want to share, although I guess I can understand concerns about 'user conflict' as there are still some knobs who don't yield to hikers.
With all the acreage in FP it is absurd that the city does not go out of their way to allow a singletrack trail to be built by, and for, mountain bikers. Look at Falls City, Post Canyon, and the incredible trail system on the westside of Bend. When you build it, they will come. And they will also maintain it, respect it, etc.
If I win the lotto I will sue the city, demanding equal access to public trails. I am being discriminated against the oppressive majority and am sick of the constant hate crimes committed against mountain bikers!
I'll shut up now.
