OK - I feel a little better now.  Apparrently this guy was just a jerk.
I agree that when you have no choice but to fish in a group, you just have to deal with it and hope that everyone can drift in an orderly manner.
Good idea auntie - my 125lb rottie may need to accompany me on a few outings.  Only problem is that he loves to swim.  I think 30 degree weather may detour that a little though.  The other problem is that he is very friendly.  But not too many jerks are going to push there luck and find out...
I'm still not sure packing a gun is wise.  I do have a temper and really don't want to shoot any body.  Having a gun can make you push things farther than you normally would.  Besides, he may have one too - or be waiting for you at your car with his...
I really don't mind sharing a hole with someone as long as they show a little respect.  In fact, when fighting a monster chromer, nothing beats that envious look from the guy upstream from you!  And a lot of guys will be kind enough to help you land it.  
I'm always ready to learn something new or share something with someone who is learning.  But I normally do prefer to avoid crowds (ie anyone that's not with me...).
Thanks for your input!
