They are not traveling together. I drove over to Joplin and stayed in one of
the two motels they were staying in. (it is 100 miles from Bartlesville)
They started coming in about 4 pm and were apparently glad to see me.
I found them very friendly. I started out after about half of them had
left in the morning but did not see very many of them along the road, and
some were actually going back toward Joplin (perhaps to see some point of
interest they had missed). When I reached Tulsa I turned back north and
arrived home about noon. Part of this may be due to the fact that there were
at least two different routes, and maybe 3, that old 66 took over the years
before I-44 was built. Some of it is good 2-lane road, some good 4-lane road
and at least a few miles is a single 8-foot-wide slab with dusty gravel on
both sides. I stopped to talk to some folks working on their driveway in this
stretch and they told me that quite a few old Volvos had passed and several
of the folks stopped to talk to them. I was pleased because in spite of being
a native of northeast Oklahoma, I had some trouble picking out the route,
and until I came upon these folks I was not sure I was on the right road.
In that area much of the old 66 shares the same route as US 69, still in current
use. In fact from around Vinita west almost to where US 60 and 66 split,
60, 66 and 69 share the same route although 60 runs east-west (Norfolk to
LA), 66 runs northeast-southwest (Chicago to LA) and 69 runs north-south.
BTW 60 (which runs through Bartlesville) crosses 66 again at Amarillo).

So in answer to your question I would say "Lay in wait for them, probably at
their motel." At least that is what I did. Susie enjoyed the trip also, in
spite of the fact that the Yellow Peril doesn't have AC and it was around
100°.
