Didn't know where to post this, and haven't found the topic with search, although I thought it would be there. I just acquired an older Honda Civic, and I have an old car rear rack, but I'm concerned about the plastic rear bumper flexing with a bike rack hanging on the car. Anybody have experience with mounting a rack on a plastic bumper car, or maybe a specific brand that works? Most cars have plastic (covered) bumpers nowadays, don't they? While I'm on the subject, some years ago I saw a few people that had built bike toters for their small pickups using construction lumber -- 2x6's, or whatever. Anybody seen a diagram to build one of those? They looked like front wheel holding racks.
