Woo hoo! Three forks saved the day!

Traveling due West I ran head on it to worsening weather. spun around and tried to get back in the clear but the sky opened up and the worst rain I've ever encountered began to fall. Flash flood stuff. immediately headed toward the closest airport (Three Forks). Landed with plenty of thunder and lightening. Moral of the story. You can watch the weather very closely (I DID) and still get bushwhacked! Thank you Garmin!
