Well, the official logo's up on the site. (www.singleridersonline.com)
I drew the logo by hand (mouse), using only a base font behind it as a guide. Let me know what you all think!
Logo wear (through Cafe Press) would include the "SRO" portion only, in order to keep it more subtle about being a "single rider".
I'll post updates to this thread as the site progresses.
Thanks for looking!
