Way too often, a road is only signed with it's county road number and my mapping software/maps show a road name (West Bumfook Rd).
I use a Delorme topo atlas and its great for SR's, TR's and dirt roads. Many township roads are using signs with the roads name without the TR listed. Delorme only lists them as a TR. This map will work good to fill in the blanks for me when I need the roads name, not just the township route number. Might come in handy finding my way to work sometimes too.
