As you probably know, on the weekends the PPA allows the "church crowd" to park in the bike lanes. If this rules must endure, at the very least please designate these roads bike priority lanes (clearly marked and ideally painted a different color) so that motorists know that, hey, we cyclists would happily take the bike lane if we could, so please slow down and enjoy your afternoon.
