All of this is great info, especially because once the Speedster/Spyder is tow-bar-attached to your tow vehicle, most likely it will disappear from rear view mirror view (maybe the convertible top will still be visible) so making sure that the bar is secured to the tow vehicle (with safety chains and cables) and the Speedster/Spyder is secured properly to the bar (with safety clips and cables) is pretty important. That almost seems obvious, but there is a lot of stuff to watch out for and make sure is right before you head out. After a while and a few tows it all becomes easier (you develop a routine) but the first few times out can be nerve wracking.
Even after a lotta tows, you can still forget stuff - I still wonder what became of one of my ramps between Carlisle and Rhode Island on a return trip from a Speedster gathering. Someone on I-78 must have been ducking and weaving to avoid it and for that I'm truly sorry. I never knew it fell out of the trailer until we got home.
Don't be like stupid Gordon - Secure everything properly before you head out.
