Finding Adult Friends

Tarra
Does anyone else find it hard to find adult friends or other married couples to hang out with? My husband and I are both 24 and have been married for a year and we find it so hard to find other people to go do things with outside of our family. I feel like all of our friends are still stuck in high school, even the married ones. My husband and I work out butts off we just bought a house and want to start trying for kids soon. I feel like all our friends have no responsibility and just want to go party all the time. It's just frustrating we want friends to have over for bbqs and go on double dates with that are similar to us and where we are in life.  Where are these people hiding?! lol any tips?! Or am I the only one that feels like it is hard to find mature friends at 24?
