cl. 2 has become a catch-all. There's also 2+, which is actually the rating the slalom folks assigned to my local paddling/poling area.Level makes a difference. I've seen that 2+ be anything from (my opinion) a 2- to a 3+ when it's howling. I've paddled it from 370 cfs (cubic feet/second) to 5800 cfs, and there's a huge difference in skills required, speed, danger etc.. Familiarity breeds comfort on a rapid. First time is potentially scary (though in an invigorating way, especially for the kids who don't have a mortgage, job, kids etc...),3 runs in you're having fun, and 50 runs later you're playing every feature. It'd be good if you could find someone familiar with the run and go with them, or at least get a detailed description. Generally from what I've seen, AW (and possibly your guidebook, but note disclaimer "possibly" lol) rate things higher than those that paddle those runs a lot do. Often a low level is slower, but creates issues with hitting rocks and capsizing, especially when you're new to this run.
We've got a local run that had 3 cl. 4 features until the "streamkeeper" decided to downgrade it to a 3+. Reason being, during flood conditions the local authorities would block parking on cl. 4 runs....but not 3+'s lol...
Anyways, don't get scared off. Scouting is half the game, kids absolutely love this stuff, and it was for 10 years my favorite activity due to the skills that needed to be learned. Now that I'm where I'm gonna' be, not slow, not fast...kind of half-fast ;-), I found something else to suck at and hopefully improve at before I'm too old. I ask these types of questions on the bicycling forums...
Generally a guidebook rated 2 should be fun, as long as your kids can actually help, and are adventurous. Main things, if you do lose your sheeeit, try to stay to the side or upriver from the boat. You don't want a waterlogged canoe pinning you into a rock. Stay the hell away from any wood (trees/branches) in the water (these are called strainers.), if floating downriver, try to float on your back, and keep your sneaker wearing feet aimed downstream, they're your bumpers. Try to hang onto paddles, etc. SCOUT SCOUT SCOUT first. If you have an issue, it's good to have a plan, large eddy to try to get to, hopefully a pool, at least a common river bank, so you're not on one side, your kid on the other. Dry-bag, towels, small first aid kit, etc... Have fun. What has you nervous today will have you laughing down the road. Trust me on this one.
