When you do hit CSUSA, be sure to check out the back room! They have everything from black and white ebony mill blanks to full sized exotic lumber, not to mention the clearance rack! If you have some extra time, I'd love to have you guys swing by my shop and we can create some havoc!
Also, if your looking for more than just penturning supplies, there are a couple of stores around like Timberline Tools that has some pen stuff, discount tools, and some cool large chunks of exotic woods...
For your next trip you'll have to make an appointment to see a 12 foot CNC lathe in action! There is nothing really like watching a full sized log being whittled into a banister in a matter of minutes (I forgot the companies name but if you are interested I can try to find it for you)
Other than that, unless you have a desire to go skiing, Provo gets boring during the winter...
