InstallFests and monthly User Group meetings are the way to start. User Group meetings allow you mingle and exchange information with like-minded individuals. They are often the source for excellent technical presentations by members or visting vendors.
Many groups maintain informative websites and mailing lists to share technical information.
And lest you think it is all technical interaction, some groups hold regular social events and parties. So get out there and get involved. You'll be glad you did.
