Well, I managed to pop into Mogo (Fossickers Permit in hand). I thought I'd just hit the entrance to Mogo creek and walk up it (not far from town). Wow, I got that wrong! It was really overgrown and boggy and not really worth bashing through. Which was a bummer. I did manage to drive through the forest a bit and hit another creek, but other than a leech and some pyrite, nothing worth mentioning.
I suspect if I was willing to walk to Mogo creek from a different point it would have been different, but I wasn't really equipped for navigating a through the bush.
Anyway, good to get out there and to drop into detectaden and buy some Christmas goodies.
Here's to more luck with my next visit.
