My suburban town has a ban on riding bikes on sidewalks, but it has never been enforced. Local bike advocates have complained that the ordinance discourages kids from using bikes. Finally, the town decided to rescind the prohibition and, as part of that process, held public hearings on the proposal. Well, someone at the Senior Center must have lobbied the grey panthers to show up at the hearing en masse. (I'm a "seasoned citizen" so I can poke fun). Person after person testified that their lives would be in peril if bikes were allowed on the sidewalk. Never mind the fact that the recission of the prohibition would not result in any change in actual sidewalk use, the proposal was shelved pending further review.
My prediction is that the town will keep the ordinance and continue to refuse to enforce it.
