Has anyone actually biked Union Avenue? I grew up in Laconia (LA as I like to tell people) and used a bike as my main form of transportation all the way through high school.
People can already walk and bike on Union Ave. It's not that exciting (or hasn't been to me at least since Goody-Good closed) and has so much traffic and so many intersections that it would be more an endurance test than a pleasurable ride/walk/whatever.
A major part of the appeal of recreational paths is that they are NOT local roads. Rail-trails have the added benefit of being generally flat, no sharp curves, etc. that help to make the trails available to all ages and many modes of transportation.
Underneath all of the over-the-top hyperbole, DJS does make valid points. The trail should be constructed in such a way so as to respect the rights of lake-front property owners. Look at the bright side, if the trail goes through and properties get trashed, then property values and taxes should go down...right?
