The elephant in the room here are the NIMBYS and "Friends of Hailey Park" , fitting a bell won't help for this case because these people aren't really objecting to fast cyclists, dangerous cyclists, or even cyclists , they are really objecting to people who are not " them" using "their" park. "many residents who use Hailey Park, which the Taff Trail runs through, were concerned as it was a place "where children should be able to learn to walk and people walk their dogs"." There is a section of Hailey park set aside for "people to walk their dogs" ( We know what that that is a euhpanism for ) and the Taff Trail doesn't go through that area. and as for fitting a bell being an answer that's not going to appease Mr Davies ( of Windsor!!!!!!) because "Very few have a smile on their face" and if a bell is used it's seen as "ringing their bells and expecting pedestrians to leap out of their way." The Taff Trail is 55 miles long, and is populated by cylclists , walkers, horse riders , those taking their dog out for a crap , pedestrians and picknickers , the busiest part of it by far is the mile that goes through Sophia Gardens, how is it then that the vast majority of the ( not many) complaints come from the mile that runs through the area of the "Llandaff Residents Association " and Freinds of Hailey Park" ?
