An poorly advertised Facebook poll hardly seems the right way to decide what to build in a public park. I never saw it, for one...
I know many people have been calling for a disc golf course in that area for quite some time, including written and email requests from myself personally. I believe that it has also been brought up by the local Disc Golf club, the Columbus Flyers, to the city on more than one occasion also.
I'm not against a velodrome, but I think more people would get use out of a disc golf course.
All the courses in the area are well used, but none are right downtown, and OSU's course is the only one that easy to get to via bike.
I actually like the idea of there being a velodrome in town, but this doesn't seem to be an ideal spot, despite it's location relative the bike path. Seems to me, closer to OSU (Fred Beekman park for example) makes more sense.
What, if any, are the issues with people wanting to race and/or train while kids want to ride around for fun? Putting this smack dab in the middle of a family-based neighborhood park would seem to create those issues.
Not to mention the increase in the hipster quotient for downtown, which is already through the roof.
