I get used to stuff in the way and find new stuff each day (see above) by riding regularly in the 15 th St cycletrack.
As far as I can tell, there are no rules once you are South of Mass Ave. Paint, bollards, shouting, and bells seem to only be obstacles to future obstacles (parked cars or a gaggle of joggers who are miffed you’re in the bike lane). I may start riding my cross bike to work so I may portage over the cars. Parts of the pavement remind me of off-roading anyways.
