I used to navigate by Thomas Guide around town. It’s a book of maps with pages, grids, and an index. Look up the street name, it gives you a page and grid. LA county is about 200 pages of maps.
I trained all kids and employees on how to use it. Put the page and grid on all my maps.
It’s dead now. To buy Thomas guides for 5 or 6 counties probably cost more than a simple GPS.
GPS is great for around town on a bike.
