Thanks for putting this together Scott, looks to be a fun day. I'm also going to see if I can't get the wife and kids to come along as well seeing how it won't be so much about doing the bumpy stuff.
Mr. Tibbs, we might also consider doing the Wendover portion as well just to chop it up a bit more and use staying in Wendover as a carrot of sorts to get them to come along. And if I lose a dollar or two, oh well!!
AJ,
Seriously, do a google search on "redneck toilet" and you should get plenty of ideas to accomadate the misses ... Just think 3 dollar toliet seat at walmart and a 5 gallon bucket with some spare plastic bags and your good to go.

You can even get sophisticated with it and find a creative way to firmly attach seat to bucket if her balancing skills are so-so.
