Respectful distance

We were walking to Terezín on a Google mapped route, but came across an asphalt paved bike path. It was the hypotenuse to the right angle. There were old chestnut trees.  Some saplings were staked up, filling in the gaps where the old trees were down. The wheat field was ready to be harvested. The thistle was making a stand. The bees were attracted to the purple blooms, as was I. How far had they flown to find this delight? Not as far as me, I’ll guess.
