Looking at this story about Minnesota’s " Name a Snowplow contest" made me think that we could be a bit more creative than “Laser 1” and “Laser 2” If nothing else I would go for “Momma Laser” and “Baby Laser,” with something like “Cousin” for the other older model.
We should definitely do this, just make sure laser stays in the name.
So when booking time
Laser (name) - (reserver’s name)
I might suggest Catoptrics and Huygens
I have been calling the new large laser Big Mama!
But may be they should get first names. Their last name could be Fusion. McFusion? Fusionstein? Fusionarelli?
