Norbiker David Marcus started mapping major roads in Norwalk. CLICK TO VIEW MAP. What’s really good about it is that he color codes the routes with detail, like “has shoulder,” “path,” “caution,” “dangerous,” and “recommended.” It’s an early and good start to developing a comprehensive cycling map. David grew up cycling in King County, Washington, a very cycling-friendly area, and knows how to rate roads. Some posts ago I mentioned the Madison, WI map. Here’s a link David provided to the King County map. . It’s another great one.
