It was a cool moment, but I didn't want to have to deal with a spider bite to end our evening, so after getting a few good shots, I closed up my camera and used it to bat the spider towards the garden. He was very slowly letting me heard him away from the kiddos, and Audrey had already lost interest, but Henry remained at my side (loudly declaring there was a "BUUUUUUUH!" and making it clear he had no intention of letting it out of his sight).
So as I'm batting the spider towards the cover (and fence) of my garden, it decides it's done being prodded, turns on a dime, and with unexpected and surprising speed, starts making a bee-line towards the creek... which just so happened to be behind us... behind Henry... and our big Bubba was not going to deter him from getting back to his hidey-hole.
Seriously, I had no idea that fuzzy thing was capable of moving that fast. I barely had time to sidestep and scoop Henry out of the way before it would have been all over him.
Needless to say, it now resides well outside our yard, hopefully relocated to a stomping ground appealing enough to keep it away.
Note: no spiders- or dogs, or babies- were harmed in this story.
