I picked up both race cars, (plus another one hitchhiking along with these 2), in a ziplock bag. There is a note to leave the cars in the bag, but I think the note means for the individual ones to not be taken out of their little baggies, not that they are to travel together, right? Let me know what to do with them, and I will be glad to send them on together or separately.
Unfortunately, I too, didn't get the note that they wanted to go to the LA area, and am heading back to SE WA State. But I will try to get them some miles as soon as I hear whether to keep them together or send them on separately.
A friend is heading down to do the Route 66 Series sometime soon, so I will see if they can't take them along and drop them there. There is a series of 6-8 "Cars" caches along the old Route 66 too, but none are large enough to leave this TB in.
