Side note... we got one of those last year and now we use it by default over making a fire in the pit. So much easier and cleaner... and you aren't dodging smoke with every shift in the breeze.
Maybe... but its consistent so I know where its warmer or cooler. Maple Valley was the warmest spot today that we saw. I am pretty sure our car we were driving today is really close to reality just based on years of driving it and intimately following weather.
Yea definitely do. Interesting, micro climate because I have gotten 50% more snow than SeaTac in my 4-5 years here. I stay way colder than neighbors. For ex: I ran 7 degree colder than @Blizzard777
