I've learned over the years "that just about everyone, when it comes to guns, cars, fishing, hunting and so on" is an "expert" when it comes to giving advice and you might be, but the "stranger" doen't know that. On the other hand who are you to give unasked for advice and chances are you would look askance at someone doing the same to you. There are of course very knowlegable people in all aspects of their "hobby", but if you might be standing next to one it is rather difficult to tell (is he for real or just full-of-it)? The bottom line, don't give an opinion unless asked for-this in many instances includes friends and relatives-it can easily becomes mis-interpreted. Most people on the other hand are very appreciative of your opinion if given when asked. --- John Can.
