Update (December 2012) I have now turned the Center Line Gallery into a group gallery in which you can download photos yourself. Be sure to give yourself credit, and provide any relevant information (where, when, who, that sort of thing). As administrator, Photobucket will ask me to approve any submissions (in order to keep out the riff-raff and anything less than appropriate), but it is as easy as that. Keep riding and bring on the photos. Not neccesarily wanting to turn this into a competition, but I may search out a way to work a prize into this at the end of each year - best entry, most popular, most submissions, something along those lines. We'll see.
Update (February 2013) Well, apparently Photobucket is doing away with the group album option. I checked this morning and noticed that photos can not be added anymore, though you can still view photos - I suspect that won't last for much longer though. I guess it is either go back to the old way, where only I can add photos, or find a new host. I haven't been especially happy with Photobucket lately. Let you know soon.
Update (February 2013) Alright, so the Gallery in Photobucket is no more. I have decided to move it to Flickr which should actually make it easier for everyone, and anyone, to contribute directly. Click the link below:
Now that you know what the Center Line Gallery is, you can jump to view the photos by clicking here.
