I have been using one of these for quite a few years now and they are great. Collapsable chairs are easily carried along with camera gear, coolers and anything else within reason. I find bungy cords are helpful to secure your load. They now come with larger sized wheels as well which are great for uneven grass areas at many of the airports and certainly at Oshkosh. Widely available at department stores or sporting stores.
Age has a way of tempering masculinity!
