Any other teams doing this?
We've got a bunch of sailors doing this - actually, me, the Mr., son 3 and a sailing friend. Almost turned into a family team, but son 1 could not get down from uni.
Transport could be interesting, might depend on a bicycle, as the friend may have limited leave of absence from domestic responsibilities, hence may be unable to hang about and ferry. Only one other car driver amongst the rest of us.
In fact, the entire endeavour is likely to prove interesting.
