Hey, if you are looking to kill a couple of minutes check out the flyers I made while killing some time myself.
The files are too big to post here so jump to my blog to check them out.
Disregard the rest of the material on the blog. I have been playing with layout and posting. Eventually my blog will document how through commuting to work and running errands my bicycles pay for themselves. Plan on using it more for a personal record and something to play with more than anything.
Feel free to poke about. If the flyers, or the blog give you the urge to spout, good or bad, do it.

rad. saltcycle has a directory of event fliers over @ http://saltcycle.wetpaint.com/page/Fliers feel free to browse it. though, I would add "SLC", "Salt Lake City" or "Salt Lake" to your fliers above Critical Mass to give it more of that local community feel... then maybe add the fliers if you wish to the list.
