I hate horse flies as well. Big nasty creatures.

That garden is massive! That does look like a lot of work. I can't imagine tending it when its super hot outside. I don't know where you're at but in France it seems like it hasn't stopped raining this spring and summer. We can barely get a decent weekend with sun. It's great for plants though. That would make your job easier from a watering perspective. Doesn't help with all the other work that goes into tending the garden though.
