I was browsing the local Craigslist Rideshare section, looking for someone to tag along on an upcoming road trip when I came across this post:

I am a nudist that will be travelling, in the buff, west on I70 to Denver and then N to Cheyenne and then west on I80 to points west starting tomorrow. It would be fun to have a HWP female rider that is open minded and willing to at least put up with my hobby even if not a practioner. I will be stopping the night somewhere in Wyoming and then moving on. I'd like someone that is willing to split gas and lodging costs if possible. I will leave the Wichita area tomorrow morning between 8 and 9 am.

Which makes me wonder: Is it legal* to drive in the nude?

*If relevant laws vary, then let me limit the scope of the question to the state of Kansas, USA, where the post was made.
