I have a motorcycle story. We took a really long ride, but I'll make the story short.
A few years ago Brenda and I set out for San Diego. We only had 19 days to make the trip, and we had a few lay overs to visit the kids in Colorado, and also to visit Brenda's aunt and uncle. But the rest of the time we would be on our bikes. Average ride distance per day was about 500 miles, but at least three of them we put in over 720 miles.
The one thing that we found out is that if you ride for only 100 miles at a time, then take a short break, it's not that hard to rack up those 500 mile days. This was our route: MI to Denver, then to Zion National park, then Las Vegas, then San Diego, then north to San Francisco area, then we turned east to the Bonneville Salt Flats, turned north to Jackson Hole & Yellowstone, then east to Sturgis area, eventually arriving at the west coast of Lake Michigan to take the ferry to Ludington, then home. It was one of the greatest rides I have every taken. Great memories.
