Bicycle facility signs

This may be old news to most of you but it is new to me.  The 2009 Manual of Uniform Traffic Devices has bicycle facility signs nicely grouped.  Of especial joy to me was the R4 11, Bikes may use full lane sign.  I'd like to see about a thousand of these posted around Tennessee.
