Right now, in Utah, I can legally carry in churches, bars, all public schools, all state, county and city government buildings (except specific secure areas), intrastate public transportation, sporting events, polling places, public gatherings, city, county and state parks, etc. Why on earth would I want to support a "uniform law" that would undoubtedly make many of these places "no-carry zones"? Certainly not to make it 'convenient' for those who don't want to expend the effort to research the laws of the state(s) in which they might carry!
