Funny you should say that.
I’m in western Maryland where orchards abound and the phone I’m reading FR on just buzzed like mad to tell me there is a freeze warning in effect.
All the fruit trees are in blossom.
Grim.
When I was a kid I remember them using smudge pots to try and avoid the freeze.
Not sure what they do now, if anything.
Probably more fans, but smudge pots still get used occasionally here in Oregon.
