When: Sometime during the night
Prime Suspect: Bambi and his cohorts
Looks like the deer discovered one of my patches of Rainbow Chard. [Not hard to figure out which side of the patch they munched on, is it?] I'm glad I had gone through and harvested a bunch of it just 3 days ago.
Now that they have discovered it, no doubt they'll be back. Bon appetit, Bambi and friends!
