Good to hear of a welcome rain!
I must say we got a real soaking the day before Canada Day, and I was really glad because of the same issue, fireworks here on the edge of the woods is insanity, and although we had enough rain recently we did have a dry winter with little snow, so there's more than plenty dry wood around to catch fire if it wasn't well hosed down by mother nature.
It was a lot safer here when fireworks were illegal, people would come out and shoot off their guns instead.
Now every Tom Dick and Harry has to fire off ten kinds of who knows what to make his own show right in the backyard....
