Yes we know that plan isn't going to work for them. They might end up with some good stories though! I did the same as you. I bought all of Sam's tracks for $100 or so and found a free version of Kevin's from someone here on AdvRider. I had both open on Gaia on my phone in different colors- Sam in Blue because he's "true" and Kevin's in red because he is often portrayed as the "bad guy." My little joke. From Damascus where I picked up the TAT to Utah, the two sets were like 90% exactly the same, and where they did differ there was really no qualitative difference in the riding. In the few places they differed it was nice to be able to have a choice. When they differed in the morning and I was fresh, I would generally take the longer option. When they differed at 5 PM and I was exhausted, I'd take the shorter option. They always came back together in 10 or 20 miles or so. After Colorado they are almost totally different. With a little overlap in the beginning of Utah and the end of Oregon. I don't understand at all why someone wouldn't run both sets at the same time. Plus more than that in fact. In Virginia, NC, GA, eastern TN I had the SEAT tracks open in a third color. In Colorado I had the COBDR in a third color. Same in Utah, I had the UTBDR open in a third color. In fact in Utah I mostly took the UTBDR instead of either TAT to get to Green River. Although there is overlap between those three as well. Anyway, everyone has to ride their own ride.
