Not exactly "backyard" but....
Yesterday, I went out and had breakfast with an old friend -- we hadn't seen each other in a while. I was zooming along, late as usual. Google Map told me to take the interstate and hop from one exit to the next to save time.
As I was changing lanes to take the on-ramp, I noticed something dark fluttering just above the passenger side window, and, in the side mirror, a length of spider web and a large - maybe 3/4" - garden spider (Orb Weaver) desperately clinging on to the fortunately thick and sturdy structural webbing in the 50 mph wind. Then I was going up the on-ramp and the spider relaxed, so I told her to hold on because we are getting on the interstate! Once I merged on, the traffic was, let's just say, going MUCH faster than the posted limit, and I was going faster and faster, one eye on the poor clinging spider flapping in the slipstream.
Fortunately it was a short trip to the next exit and, once in local traffic, we slowed down, and I saw the spider, pulling hand-over-hand ..err.. leg claw-over-leg claw, heading for the side mirror. I realized she was trying to reach her hidey-hole behind the adjustable mirror, inside the side mirror casing. I was watching her out of the corner of my eye, cheering her on as I drove, and actually blurted out "You made it!" when she reached and slipped behind the mirror... but then we stopped at a red light and the spider started creeping out. I was telling her to get back in there, the light's going to change any minute! Hold ON!
Well, she knew what was up, apparently, because as soon as we started moving she ducked back behind the mirror where it was safe. haha. What an adventure.
