Hello everyone,
I have just created a new public packrafting facebook group to help facilitate trips, if you are interested, please join: https://www.facebook.com/groups/233365700332496/
My attempts to organise trips via forums has usually been unsuccessful, especially at very short time scales as a.) forums aren't checked as much and b.) most rafters I know do not use them. I have however found forums gold, for information, knowledge and opinions (not what the fb group is aimed at).
Cheers,
Jeremy.
