Bubba2, ''gobsmacked'' is an expression we use here to say we are speechless. A 'gob' is, generally speaking, one's mouth, and smacking your mouth is one way of stopping it from uttering something nasty, usually. We have candy on a stick here that is large and sticky, sometimes known as 'all day suckers,' but also known as 'gobstoppers.' We use the terms ' shut your gob' and 'stick that in your gob' as a way of saying, 'shut up.' You certainly got the flavour of the term right in your second post, good on ya.
Wayne, I have just started using a detector and I have much to learn yet. I hope the next time we go out I find my first nugget, but as I get older I find it more difficult to learn this new technology, though I will be trying hard to get a handle on it.
Mikie, no we didn't find any gold on that trip, sorry to say, it was our first time with a detector, and put the day down to education.
Sheila.
