I won't leave y'all in suspense any more. :)
Those were some good guesses. All of you came pretty close.
It was the spray from a semi truck on the highway. I was trying to get a picture of the wheels, but I didn't snap it quite quickly enough. It's one of those that's so weird I like it. Know what I mean? Or am I all alone on that one? :)
Anyways, not much has been going on around here. Just the usual. :)
Oh, and for those of you who are curious about the weather, it's currently 81 degrees. Ahhhhhh... :)
