Okay the tally so far:
 
1 for  www.utah-astro.com
1 for www.utahastronomy.com
1 for www.utah-astronomy.com
1 for www.utah-astronomy.org
1 for www.utah-astro-pics.com
 
So... lol, no one has gotten more than one vote.  :)  Unless I miscounted which is always a possibility.
 
A coworker sugessted using www.utastronomy.com... which I think I'm liking the best so far.  My reasoning... I think .com is the most common extention, and even tho it's supposedly for a commercial site, it being the most common would be the easiest to remember.  I don't really care for dashes or other punctuation in URLs, seems to kinda clutter things up.  I do like short... and yet astro... somehow reminds me of the Jetson's dog... :) and Astro Burgers... LOL  I like the longer term potential of utah astronomy, instead of having the pics in there. 
 
I guess what Chuck said is right... whatever it is, it'll work. :)  And anyway... bookmarks are easier to use than spelling out the URL... hehe.
 
I'm still waiting for input.. I'll probably buy one later today or tomorrow.  :)
