Yes the possibilities are endless. The Beeb and their "Container", BBC again with "By Any Means". My inspiration was a childhood book called "Paddle to the Sea" about the native American boy who carves a wooden canoe and sets it off down from the mountain snows of spring through rivers and the Great Lake to the ocean. Yes some sort of sponsorship would be good to help with the inevitable "dead-ends" that will need finances to get out of. Perhaps customs or other charges that it would be unfair to expect the current " handler" to pay. We are trying to do a "By Any Means" , ie scrounge lifts, transport, time , and effort from total strangers ( except those known to us via the forum(s) . Some very generous offers have already been made and some cash expended while doing trials in the UK, notably Norry, Stavros and Steamboat Phil to name the pioneers. Now we need professional standard help I think it could snowball as Roger suggests.
