So back in 2010 while riding through Bickelton Wa, I stopped in a small mom and pop store and discovered a free map that showed hundreds of motorcycle friendly routes to travel. Not just a highway map, but a map that gave details, gas stops, number of turns on the road and literally hundreds of bike events and dates all over the area.
The images I have posted shows the maps areas and the highlighted area is of the map I am holding. They provide the maps free of charge online to download
You can obtain a physical copy from them if you call and talk to Lilly. All the maps for all the areas are only $12.50 and $5.00 more for a second set. It's a mom and pop business that does this for the love of riding. The new 2025 maps come out in May but the 2024 which are equally good are available now.
I can't attach physical maps...but if you go to the link you can download them directly from them. Enjoy!
