Re: why fish
I really find it odd when someone asks a question like "Why Fish?". Do they also ask people odd questions like why play sports or why watch a movie? One answer that really can work out well is to invite them along to try it. Once they experience the outing they usualy will know why.
Another answer would be to ask them a question back; why walk along a stream on a beautiful morning, why spend a day on the water, why challenge oneself.
I feel ceartain that each of us should take the time to answer anyone that asks the question and look at it as an opportunity to convert a non-fisherman into someone who would support our sport.
Why fish? Because, I live.
