I'm planning a trip up to Big Bear and really want to try my hand at freshwater fishing, but I really have no idea what I'm doing. I only have saltwater spinning rods, is there such a massive difference that I can't use them in freshwater? I'd like to avoid having to buy a whole new set up, but I will if necessary! I'm interested in catching largemouth, trout, and carp at this point, and I would be going out in a boat, not shore fishing.
