The No Bikes signs actually request that you walk your bike through the paths. They are narrow and sandy and are used by walkers, dogs, family groups, etc. Sanderling does have a large Owner/Resident population, and lots of us are well over 65. I've been bumped and knocked over more than once by people riding too fast and without caution. I'm convinced that people lose their ability to read when they cross over the WMB cause I have yet to meet up with a biker who actually was walking their bike through there!
