as anyone who has one will know, if you need to carry one any distance its a real pain....
yes you can blow it up at the car, attach the carrying straps and then walk to the water - but its a bit of a pain
i thought about getting a big rucksack to put the tube, flipper, pump etc in but then i was at the beach at Dornoch on Saturday and saw someone with a bag that i thought was idea - one for putting body-boards in ....so i got one....
its marvellous...( its the size to cope with 3 boardy-boards or one float tube)
i can now get all of my stuff to the water in comfort and in one trip !
