Gee Catfish I'm sorry I slept through yesterdays posts and missed the hole thing until it was to late.
I actually added a new page to my website Sunday night about brining and although I may get some argument about it from some people my personal experiance and experiments over the past year are reflected on the page.
You can over brine food! I also have a table of MY recommended times for bring meat.http://www.deejayssmokepit.net/Brining.htm
And as a side note - if you do suspect you've over brined or for some reason didn't get to smoke the meat and it sat in the brine to long -you can remove some of the salt by rinsing it off and throwing it back in PLAIN water over night. It won't take it all out but it will remove some.
Again I appologize for not being here for you last night.
