Thanks for the link for the kit, and all the general feedback. I had not thought about going under at all. I really like this idea and will definitely explore it as an option with the SUV. One of the local scrap yards is open on Saturday for a few hours and has a wide and open parking area, so I might just use the trailer then. I'll probably tape 'em together though, as I want to get 20+ sections.
Great feed back and great ideas. Thanks all
