I bought a bike from a neighbor yesterday, and then promptly went to Walmart and bought a trailer for my two little ones to ride behind me. I tried it out this morning. It was alot of fun! I haven't been bike riding in literally years. It was a smooth ride, but wow, what a workout. William weighs nearly 25 lbs, and Kaitlyn is 35 lbs. You do the math. That's how much weight I was pulling.
I never thought our neighborhood was that hilly, but when you're pulling 60 lbs behind you, every little rise is a serious strain on your muscles. (At least it is on my wimpy muscles :) It took me nearly 30 minutes to completely cool down when I was done. I haven't worked that hard in a while. It was great.
So, I decided that after dinner each night I'd go bike riding with Alan and Sarah on their bikes, and my two little ones in the trailer. I went again tonight with them and it wasn't as hard as this morning.
