Is this the same battery you've had? It's 16 years old?
Did you drain the old gas if you had any in it?
Not getting any lights tells me the battery may be dead or some mice chewed your wires. That's only the first two things that come to mind though when thinking about bikes being stored a long time.
You check you plugs, filter, and rubber parts? Probably could use fresh oil too.
As for a Father's day ride I wouldn't be going anywhere on 16 year old tires.
