Ever since T. Boardman wrote this post about Flickr, I've been meaning to search out come local Flickr Groups. But anyone who knows me will remember that I catch on to complicated stuff pretty quickly, while the simple stuff often leaves me baffled. Well, I finally got a grip on Flickr Groups.
For anyone else who needs a roadmap, here we go:
Join Flickr and Create Your Account if you haven't already done so.

After you've joined and logged in, click on Groups:

In the "Find a group" search box, type the name of your local community and state, or any other subject of interest to you. Click search.

Flickr will find groups related to your search terms. Click the group name.

If it looks like the right group for you, Click on "Join this Group?":

Assuming it is what you want to do, you can go ahead and click yes, you really want to join this group.

You probably joined the group because you wanted to add your own images. To get back to your own images, click "You"

You'll land back on your own "Your photos" page. Double click on a photo that you want to add to the group you just joined.

In the horizontal menu displayed between the photo name and the image, click "Send to Group" ( You have no idea how long it took me to find that!)

Click on the group name to which you want to send the photo:

Click OK to confirm:

Done!
