I was in my shop today when the unmistakable sound of blades beating the air made me walk out side.
I looked up as 4 helicopters slowly flew right over me in formation. That wasn't so strange, but these helis proceeded to fly a grid pattern right around my shop for the next hour... slowly.
My sister called the shop and said she had the same four helis flying over her house as well in the same slow grid pattern. Pretty weird.
Made for a nice photo opportunity though. Might need to break out the tinfoil!
