Yes, we get pretty cold here too. Usually by now I've turned on the swamp cooler but it's still pretty chilly although this week we will be lagging you a bit but finally hitting 80s. I'm hoping to get my blooming tomatoes and peppers into my garden (chances are they'll be really pissed off and drop their flowers LOL)and heat
I've been looking at sizing and I'm getting final line lengths today, gotta climb into the attic (again), looks like 48k and a 5 zone with bridge with a 9+9+9+24 cassettes, then possibly another 18 for the garage (we are not ready for that but will buy an extra port).
