I think it was this last fall. I had an entire line of geese standing at attention about a foot apart lined up completely across both lanes. It was hilarious. It looked like they were purposely trying to stop traffic. I wish I would have had a camera. It looked so comical. They didn't move until I was about 10 feet from them and even then they only really gave me enough room to pass.
Two ways to get the photos up.
Upload them as attachments. I haven't done it, but it should be straight forward. The upload attachment link is below.
The way I do it is I have a place to upload my pictures. You can create a personal album on here, but I don't know how it works, but the link to the Photo Albums above will get you there. There is photobucket and a number of other sites that allow you to upload pictures as well.
After you have the picture online somewhere, usually if you right-click on the image and select properties it will give you the address of the photo. Copy the entire address and paste it in your post. Then select the entire address and hit the Img button right above the text box. Then hit preview and you can see if it worked.
This is what it should look like when you are done.
It might take a little trial and error, but it's pretty easy. One trick to figure out how to do something that someone else is doing is to hit the quote button and it will show you exactly what they did.
