This worked well. Thanks.
I am putting together a purpose built item to acomplish this. It will consist of a fabric sling with wooden dowels on each side with handles. similar to what you might have seen to carry a bundle of logs for your fireplace. I will provide a connector for the handles to make it easier to get in the car etc. If it works I will provide more information. Might even make it out of a tartan material
As for the motorcycle problem cant help you. Someone from the above advertisers should look into designing a kilt with a Dennison Smock style flap. (British Para design WWII)
