Ya I've done a lot of stuff with meetup it's not a chat room basically you organize a hangout with people of similar interests to hang out and like play sports or go to a movie together
I've been part of a local hiking group since 09
It's pretty cool at first like many people my main concern was meeting strangers from the Internet in the middle of the woods but we shod remember that serial killers actually make up a small percentage of the population so you really don't have to worry too much about that
Most of the people in the group I'm in are more middle age Orin their 30s some getting close to 60 but I've never hada problem getting along with grown ups or older people
So I've gone on a couple hikes with them I've also gone camping kayaking andeven seunong
That was awesome and so much fun I even went on a 4 day backpacking trip with the group over spring break it was great, it was my first time backpacking but everyone was nice and very helpful there were a few people in their late 20s so they were closer to my age, it was fun and we all had fun things to talk about and got along ok
You should defiantly check it out. I actually found out about the group here on the forum when someone started a similar thread
