If I'm gong on a fishing trip I'll take 4 or 5 rods. If I'll be fishing just for the day, I'll take 2. The one I plan on using and a spare.
You can do a lot of damage in a week. Between my fishing partner and I we always seem to break at least one rod when we go on an extended fishing trip and one trip a couple of years ago we broke 3
Over time we've broken so many rods that a while back we started bringing what Lefty calls an "eventuals" kit (eventually you're going to need it
) containing an assortment of tip-tops, some tip-top cement, snake guides, rod thread on a bobbin, epoxy, some "reel sized" screw drivers, and a bottle of "Sally's". It's come in handy more than once.
