That's so awesome to see other crazy bird people! My husband flies the medical helicopter around here and the base is surrounded by dandelions, which my husband is deathly alergic too. I've been joking for ages that once our ducks come I'm going to strap harnesses and leashes on them and let them go to town on all the weeds and bugs that grow in the field around there. I was laughing about it to one of the nurses who just got ducklings and she started laughing saying she'd have to do it to. Of course since the helicopter base is right off the highway we both cracked up at the thought of everyone seeing two people, one of which in a flight suit, walking around the helipad with ducks on leashes.
