Wow, Salsacharley, that is a beautiful spread of cherries!
My farmer friend has one greenhouse just for cherries - 50 plants. They're pruned to a single stem in the beginning and tied up to overhead beams. By the time they're grown the space between rows is pretty narrow - but the cherries are all within reach without crawling. Still she has commented to me that she should charge more for cherries because of the pick time. Her customers want them, as you say there is certainly demand.
Last year there was an extra row of cherries in the other greenhouse that wasn't pruned much if at all... and I know what you mean about crawling.
