1:24,000 = one inch for 2,000 feet or about 2.5 inches to the mile. Easy enough. I designed a bunch of dams/reservoirs and a canal from Texarkana to Lubbock from topo sheets. $9 billion worth of project, in 1968-sized dollars.
Navigated around a fair amount of Texas hunting, but quit worrying after I memorized the areas.
Sorta like flying a 172 from Terlingua to Georgia. After a couple of trips, I didn't need Sectionals any longer. Lotsa landmarks.
Oh, about forgot: You can get scales which are set up for all manner of map scales. Again, surveyor supply stores. 1" to 24K, 62.5K, 250K, etc.
