Well, I lost another 4 hours to digging out edges because I only dug out 14'x26 (extra 12" all around). I didn't pre-measure where the towers would align compared to my existing deck posts. Turns out the towers line up perfectly which means I had to stay farther away from the deck than I originally planned. Ugh.

Good news is there have been only minor showers and not too hot for construction. Bad news is we are just starting construction. (I'll open new thread for construction as excavation is officially done.)
