I would also like to offer that the intent of the Utah Pilot is not to add any new trail geometries.
As stated in the announcement (emphasis mine):
volunteers will be tasked with updating attributes of existing trails in OpenStreetMap using official and approved sources. The Utah campaign will focus on improving trail attributes based on the trail tagging guidelines developed as a result of the trails tagging schema pilot in Washington state.
@tekim, I’d like to join others here in encouraging you to become involved in the Trails Working group if that’s of interest to you. It sounds like your extensive experience would be valuable to the group.
