Without further ado, the new double jogging stroller!
Bronwen gives it a try:
Both girls seem to like it:

We've already gone on two evening strolls with it, and they are doing great. The first time the girls were awesome, Lila sitting with her ankles crossed and Bronwen enjoying the ride. The second time, there was more, "Don't touch me"-type shenanigans, which T.J. and I ignored, and Lila found hilarious.
The walk ended with Lila making her baby calls (kind of sounding like a loud "Ahhhhhhhh") with Bronwen chiming in by screaming along side her. Fun times.
