Back working on one of my wild a$$ed hair brain ideas that I have kicked around for a long time but never pushed farther than a few neurons slowly crossing paths in my head...
All our pallets are what a would call "one way" pallets. Every entrance ( landing boards) face the same direction. Not going into the logic or benefits of that right now....
After a few years of running them (10 or so) I decided that that it would be a good idea to paint the ends of the stringers on the "open" side a vibrant color ( yellow) so any dummy could easily lay out pallets facing east or south when laid out splits... easy on the mind and the eyes.
Once we had enough of them in the rotation I figured out the paint was very useful in loading trucks where the pallets were more easily placed all "in" or all "out" as desired.
A few years back it came to me that having all the strips and stringer ends painted phosphorescent might be useful in not only determining the "side" of the pallet but also useful on in grabbing them of the ground or loading when the bees were hot and we loaded "lights out."
Not sure if this be useful or not and am even more perplexed as to what the reaction of the bees will bee to the "light" coming off of the front of the pallet.
Anyone been down this road? Any hypothesis as to how the bees might react? ( Might be that the spectrum will be out of their visual range and won't matter)
