&#039;Critter&#039; up close Robert Harting, an equipment
specialist with the U.S. Army Communications-Electronics
Research Development Command, goes for a spin in his
&quot;Critter,&quot; a three-wheeled lightweight vehicle that he
drives to work whenever the weather permits.  Is it electric' Is
it a boat' Where's the rest of it'  Drivers and pedestrians may
have noticed an odd shaped vehicle motoring around Aberdeen
Proving Ground lately.  The small, white, low-to-the-ground
contraption that resembles a car is actually a motorcycle owned
by Robert Harting, an equipment specialist who commutes from
Laurel, Md., every day. Harting came into possession of the
vehicle labeled the Critter in 2002. He said it was invented in
1990 as a prototype for a commuter vehicle.  "The inventor made
three of them and then changed the body to make it more
aerodynamic," Harting said. "Most people think that I built it
but I can't take credit for it."  Plans for building a similar
vehicle can be found on the Web site, www.rqril
