Ouch. Counties in Ohio are a mix of CR 123, C-123, CH 123, and yes, CO 
123. State routes don't show up at all because we use the SR 123 format. 
New mappers sometimes change the ref tags specifically because of MapQuest.

Make sure to use network=US:MD:County_Name on the route relations and, 
if these county routes have shields, file a bug to get the shield 
renderer to support them. [1] Hopefully someday MapQuest will fix their 
stylesheet. :-)
