Excellent suggestion - have a pair of them
Sorry, but the operation of amatuer-type radio devices is prohibited while the van is in motion.
You want to hear the commentary, you ride in the van.
However, the tour guide is allowed to summarize everything said when we stop and get out - as long as the summary is along the lines of "I told everybody about what we were passing, and some funny stories too. It's a shame you were not riding with us to hear it."
This is not the time to display rugged individualism. It is the time to come together in solidarity.
Scouser supposedly knows where all the clean restrooms are, and unlike some others who are going to taking the tour, does not have an unlimited gift of gab. Grapeshot gets really, really cranky if he is forced to sit on his bony backside for too long, so leg-stretching stops are being built into the itinerary. A few folks have already identified additional committments, which meand the tour will not be stretching out for hours and hours and hours. There's plenty of leg- and other-body-parts room so your general comfort should be much better than riding GRTC
At this point the only thing we are lacking -- besides riders -- is a stewardess and some cold sodas/packages of peanuts to pass out.
stay safe.
