Trish - sounds like you need a Spanish holiday!
Yes, that one's a bravado thing for sure as there's an alternate easier crossing (the one I'd take)
It's a creek crossing worn to that extent from use over the years & a "right of passage" for some (the foolhardy IMHO)
It would just get washed out again if filled.
PS. This is in crocodile country also! so I won't be paddling in any creeks either!
