I've been exploring a new site the past day or so, and I'm finding a lot to love. It's called Outdoorzy.com, and it has some excellent resources for all the things I love to do outside, including hiking, backpacking, adventure racing, kayaking, and a lot more. You'll find trip reports, gear reviews, regional destination suggestions, even a very nice events calendar. There are even some great forums, broken down by a myriad of activities, and while there isn't a whole lot of traffic in those forums just yet, I can see them being a really nice resource in the future.
So, head on over, take a long for yourself, then create a profile and join the community yourself. I think you'll find a lot to like. Be sure to bookmark before you leave too. You just might want to return on a regular basis. :)
