Sounds like fun. Why not take 2 lane back roads and enjoy the scenery. Remember it is not about the destination.
In our case, it sorta is the destination. We are going to start in San Luis Obispo and then head North up to Reedsport, OR, then East to Klamath Falls, South down to Lake Tahoe and through Yosemite before heading back. We are meeting some family along the way so we have a loose schedule to stick to.
The original thought was to trailer out to Visalia, CA (I have a friend out there so I could leave the truck and trailer) then do that loop and drive back. But as others have pointed out, riding isn't a ton slower than driving. In my case, it might be cheaper as the bikes get much better mileage then the truck, I don't have the trailer yet, and the truck at a minimum would need 4 new tires for this trip.
Hence my question about this trip and her running higher speed. We would have to cover DFW to Visalia in two days, max. It's doable, but it's 650+ miles a day.
I'm just trying to look at all the options ahead of time.
