my favorite snapshot is the one where she's barreling into the tunnel and all you see is the force of her back legs plunging her into the tunnel and the happy plume of her fuzzy tail!!! We're so glad you guys love it!
It really does look like fun. Of course, Matilda is obviously having a ball running the whole course. I wonder what Saoirse would do. ...... She'd probably just run high speed laps around the outside perimeter. But she'd have fun doing that, too.
