...showers should be mandatory at work! I commute in so early in the morning, that I have the whole locker room to myself.
But with cycling, I've found the magic speed where I generally don't break a sweat over 1/2 hour.
Yes, they should be! At first I thought I'd have to buy a gym membership to use ours. That miffed me, since employee parking is free. But, I was wrong, the showers are free to all employees after all, so I won't have to "raise a stink" ;) about it!
And yeah I had noticed the time stamp on your AM commute -- yowzers!
