There are multiple cities hosting meet ups...you will find me @ the one in Columbus, OH: http://www.standalone-sysadmin.com/blog/sysadmin-day-get-together/
I highly recommend that if you're free and in one of the areas with a hosted event you should give it a try and stop by. Though this is my first year going to one of these events I am sure it will be a great way to connect with people in different parts of the sysadmin field.
And if you're not an admin and you've hit this post don't forget to give a shout out to your sysadmin and let them know you're aware of all the hard work they do.
