Please do not quote me, I don't want the notifications as you've been on my Ignore list for months Your post rate is over 2000/year, probably the highest in the forum. Some of it is probably useful information, but as far as I can tell, most of it is noise for the sake of noise. As an example, you had nothing useful to contribute to this thread- you know nothing about immigration procedures for this kind of activity, nor do you even know anyone who's done this.
The route/safety issues are so obvious that blind Freddy could see them, so I wouldn't regard those as a useful contribution either. OP seems clued up enough to be aware of those, and there is a standard mitigation strategy that anyone involved with long distance paddling should already be aware of.
