Actually, I was blessed to have a shower in the office. But, as I used the above said options (along with showering well at home) I realized I didn't need them. It actually takes MORE time and energy to shower at the office than to shower before I ride.

PS - I actually feel more grimy when I drive instead of riding... don't know how to explain it... maybe because my body is still kind of stagnant? (note, before anyone asks, yes, I still shower before I drive... it's how I wake up in the morning)
