We rode several rollercoasters at the new theme park yesterday, and my favorite was the one with the loop.

The rollerman carefully fed the glowing billet between the rotating rolls, monitoring the mill's gauges as sparks flew.

The rollerless paint applicator ensured a smooth, streak-free finish on the wooden panels.

She packed her rollerblades and headed to the riverside for an evening skate.

She rollerblades through the park every morning.

We spent Sunday afternoon rollerblading along the river promenade.
