I just got back from a weekend camping/fishing trip with my son, and I have to agree, the older they get, the more fun they are to be around.
Of course, on last year's trip, I did all the tying, baiting, and casting for him, but as a result, Dad got to do a lot of fly fishing down the shoreline a ways while The Boy sat with his hook full of Power Bait in the water, waiting.... Now that he's six and an Official Big Boy, he insisted upon doing all of his own baiting and casting, which did nothing but cause a lot of anguish on my end, as he went through almost an entire tackle box full of sinkers, swivels, snells, etc. and was calling "Daaaaaaaaa-dyyyyyyyyy!" about every three minutes.
I decided that for this weekend, fishing just wasn't in the cards for me. Good thing I brought a book and a half-rack of Fat Tires... Still, I wouldn't trade the weekend for a million dollars.
