I think I can safely represent the tandem teams on this forum by responding to this generous invitation with the following: "OUCH!!!!"
I've driven many of those roads. The scenery is spectacular, and desolate. That's big country. And we've ridden Lotoja, 206 miles. If a couple survived the Hoodoo500 on a tandem, it would be a once in a lifetime. Because she may never get back on the tandem.
Note: I didn't say that there aren't a few sick-os here that aren't contemplating how to talk their wives into this.
