Fired up the Lil Rambler a few days ago. It was easy to put together. Abby and Luke fit in it well...if I wrap towels around Luke's straps. I'll post a picture of them when I figure out how to do that. Anyways, I remember thinking to myself, "Self, I need to remember to put air in the tires, for they are completely flat." Or something like that. Then I took off running with it. It felt so heavy and I was so tired. I knew I couldn't go long with that heavy thing. I figured 15 minutes was going to be the norm for awhile. Then I got back and realized I hadn't aired up the tires. But I didn't think anything of it until today. Jason and I decided to go for a jog with the kids. I had put the kids in the Lil Rambler and was ready to take off when Jason said, "Shouldn't we air up the tires?" Duh. So this time we did and it rode like a dream. It was so smooth and it cornered so nicely. It didn't add any extra work to my run. I'm quite pleased with it and highly recommend it. We went around 2 miles with no problems. Abby loves it. Who knows about Luke. Good times.
