Thanks for the pics Kristi. Looks like you still had a good time.
If you want to go cheap with navigation, get a Garmin etrex series GPS. They range from $100 to a few hundred depending on what model you get. The nice part is that they all have a breadcrumb trail and compass feature, so even if you dont have street names to look at, or on the fly directions, you can still find you way back by heading in the right direction. The etrex series also has a great little handlebar mount that fits well on the R's handlebars. These devices take away much of the fear of getting lost!
Here is the entry level one:

And here is one that has a mapset in it, and its color:

This is a good place to get them online:

I've owned both the standard yellow etrex and the etrex Vista (as well as a bunch of other GPS devices, which were mostly Garmin). They are really well made and the interfaces are well done.
