I wasn’t being sensitive, and I knew the point NorCalDan was trying to make. I just thought the way he wrote his point was a bit silly. But I do need to find a pic we can agree on (and it certainly has to be something I really like!).

Well it has been a while, but I have had some more time to think about this tattoo (although I still haven’t convinced the wife!), and I have done some searching to find some cool snake tattoos. I have some ideas, but I am keen to see if other people have seen some snake pics they think look good. Apart from the tattoo being black and grey, possibly with a little colour, the only other consideration would be that it needs to look a little aggressive, but not with fangs out (again, thinking of the wife here). And it will probably be on my back/shoulder blade.
Any ideas would be appreciated.

yep, definitely mean black and grey!! (note, always proof read posts!!)

not a bad example.

Thanks for the suggestion, Buttwheat, but not quite what I am after!
Crossatwood, that is the one I heard. Apparently it is a Cherokee legend.
