I'll bet that if you looked at how a guy acts while driving, you'll be able to draw some conclusions as to the type of fisherman he is, and vise versa.
For example:
1) Corker/Low Holer/Owns the river/Feels his fishing experience is more important than the others around him = Owns the road/cuts people off/doesn't bother signaling (he's the guy that speeds past a lineup of merging traffice on the shoulder just to be sure he gets 10 more cars farther, or 2 more seconds, ahead of everyone else, after all, his time is more important than everyone elses...)
2) Throws trash out window (or lets it blow out of the back of his rig) = leaves bait containers on bank
3) Pi$$es and moans about traffic and how others are driving. Get's high blood pressure and a candidate for road rage everytime someone cuts him off = Pi$$es and moans about crowded fishing spots. Day is ruined when someone corks him. Wonders why he even bothers fishing any more.
4) Takes the scenic route - longer drive, but less traffice. Let's people merge and stops for people trying to cross the road. Enjoys listening to music / conversation with other passengers / relaxed = Works a little harder to avoid the crowded fishing holes, if he gets corked, he may not like it, but he is determined to have a good time, enjoy the scenery, and meet some new people.
So what do you think? Is it likely that these kind of conclusions can be drawn? Any other examples/comparisons? Which one would you be??
