Neal, I probably wouldn't like hot and muggy either. The thing I don't like about the summer heat, that it really is too hot for me to work outside once the temps get above 90F. I have to get everything done before the heat hits for the day, so I am always pushing. I prefer to work at a steady pace rather than pushing to beat the heat.
Spring becomes a marathon to get a LOT of work done before the hot days arrive. Then fall is another marathon to get everything done before the rains arrive. That kind of gardening just isn't as much fun as I would like it to be .... it becomes true labor.
During these drought years, temps do not cool off until after dark, so there's really no working during the evening hours, either.
Since I don't have any shade in my garden, just moving to some shade and continuing to work is not an option.
All of that said, it's still worth it.
