I tried curling at our local ice rink. They have leagues, but when they first started they had some free intro nights where you could just go try it. It definitely takes skill, like bowling. Also, like bowling, it's a real "beer drinker's sport." I like how they would just bring a six pack and set it on the ice - nice and cold!

Curling stones are heavy, and sometimes you have to sweep really hard, so it does take some physical power. Honestly, it seemed like a lot of fun, though I just didn't know enough interested people to get a team together.
One thing I did notice is that when you just wear your shoes on the ice, your feet get really cold! I am used to skates where you are an inch or two above the ice. Curling does require special shoes, but for intro night they just had us wear our normal shoes with some slip-on covers. They do it on the skating rink, which is a little different than dedicated curling sheets (though they do texture the ice for it). I doubt there is enough demand around here for a dedicated curling center, but it's nice that we have an option.
