[SDCBC] Well it looks like I am not the only one...

This was why I was pulled over last year on Mast Blvd in Santee by some 
deputy.   That street has a 3 foot bike lane next to parked cars, and a 
9 foot travel lane.  The other lane is like 12 foot.  40mph zone.   For 
some reason since no one has been seriously maimed or killed by riding a 
bike there, the City of Santee thinks it's "safe."   I routinely take 
the center of the lane to force traffic to pass in the left lane when I 
go through that 4 or so block section of Mast Blvd.  Got pulled over for 
not getting in the bike lane, when I pointed out the door zone, the 
narrow lane, and that I had the choice of "door, mirror, or take the 
lane" I was going to take the lane every time.  It ended with a "Be 
safe."  I've pointed this out to Santee a few times, and they ignore it 
since no one's been killed.   So, with that said, it looks like they're 
getting ready to repave that section, so maybe it's time for new markings.
