The Frog was ok, especially if you leaned it on the two big wheels. I wouldn't get it if you frequent rough terrain, but for the occasional rough terrain, it beats the heck out of a cheap umbrella stroller.

Found a pic of us with some of these products, on a dock no less:



One kid in the Moby Wrap and one in the Baby Jogger. We're on a weekend trip. Notice that all our hands are free and we're not dragging any luggage. This is by design :P

The object hanging from the handlebar of the stroller is a breastfeeding pillow. It's called My Brest Friend. Cheesy name, great pillow. Beats the heck out of the ubiquitous Boppy.
