Soo, finally got around to doing a drain here in Brisvegas.
I belive it is called Waa although Meta or anyone else can correct this.
So we get in there at low tide and walk through till the hobo room (not sure if this is the right name) and find it a little too deep to walk through (less than 100mm deep) but only just. We turn around and walk back and when we get to the exit the drain is just starting to fill with water (tidal) so we climb out and leave.
I didn't find it that bad, but i wish i had brought my dive booties with me so I could have continued onwards.
I do have pics but they aren't arty and I can't remember atm how to shrink em but may post them up later.
Cheers,
Mr Fish
