South Dakota Custer State Park has some amazing highways especially designed by state governor Peter Norbeck to be driven very very slowly through magnificent scenery! Needles Highway was deemed impossible to construct by its critics nevertheless it was built in 1922 and included three tunnels, 14 miles of sharp turns and towering granite needle spires. We traveled slowly at about 15 mph through magnificent forests of aspen, birch, pine and spruce. Ended up at Sylvan Lake and stopped for a splendid light lunch at Sylvan Lodge.
