When I got the 4 computers for the rovers I still had not come up with a good names for them. Loading Windows XP I simply called the first one Mystic One. That led to the others being Two, Three, and Four. The more I used that name I liked it and started referring to them collectively as The Mystics. That is their name now and I will use if for the team name next year: Team Mystic.
The name obviously comes from Mystic Lake Software, my DBA. After Shari and I decided I was retired - I promised to have a warm supper on the table for her every night - I wanted to create a DBA just in case I did pick up some kind of work. Behind our house - and across a street - is a small park with a lake - Mystic Lake. That felt like a good name so I used it by simply adding the "Software". It conveys that aura of mystery that pervades software.
