Going to work it's called The Commute. One grind uphill 'til I get to a screaming downhill (up to 30mph in 2 blocks) that is interrupted by the busiest street in town. "But Mommy! I don't wanna brake!" screams my inner 2-yo.

Going home there is a block-long hill that some days I'd swear is vertical. I've logged as low as 3.2 mph on that section. When done with that, its downhill rollers all the way home. Wheeee! I haven't named the hill, but it has my number.
