Growing up in England, I could buy OS (Ordnance Survey) maps at 1:25,000 and 1:50,000 scale for my hiking/biking trips. These were readily available at bookstores.
I have 1:24,000 scale GPS maps on my Garmin Oregon 450, but would also like printed USGS maps to get the bigger picture when I'm out touring around/fishing.
Can I buy printed maps from the USGS?
What maps do you guys/gals recommend for good detail (like 1:70,000 or less) that cover county-wide areas (e.g. Crawford County, MI). The National Geographic ones I just bought from a recent trip to the Great Smoky Mountains National Park would be great, but smaller scale (i.e. more detail) would be even nicer.
