you have to stash food and clothing at work
you have to shower before you ride
you have to arrive before anyone else
you have to strip head to toe and change everything
if you don't have access to a shower you still need to wash key areas
before having access to a shower I brought a few key items:
diluted shampoo
washcloth
small towel

be sure to clean up your wash area and leave no trace
you can do it be creative
