Bored Parents + Grapefruit order = Grapefruit picking party!

I received a order for 6 cases of grapefruit the other day.  My parents are also visiting from South Dakota.   I took them to the farm to pick grapefruit in the orchard.     They didn't complain, but I guess picking grapefruit in 60 degree sunny weather is better than being knee deep in snow and below zero weather.     The trees are old marsh grapefruit trees.   I have 11 of them in the orchard.   I am happy to find someone interested in grapefruit because the pharmaceutical industry has destroyed the grapefruit demand.
