My son and I went for a nice long ride yesterday. We stopped half way along our route at a trailside cafe for a big hot breakfast. Still, I carried a lot in my saddlebag (the one pictured a few posts up): my barn jacket, a fleece, a football, a cooler bag with 3 chicken sandwiches, a bottle of lemonade, crackers, fruit snacks, my xa (snug in a side pocket) and my M3/J8 in the other side pocket. I like to carry everything in the saddle bag, nothing over my shoulder. I've never had any alignment problems, but my bike has a big floaty ride I guess. 🙂
BTW Simon, I think Sheldon Brown's monicker used to be "Mouldy Oldie." I'd looove to have a Moulton. Oh, and a Bike Friday Triple Family Tandem. 🙂
