If you take an astronomical telescope,and a cdc camera,laptop and batteries,and go to a hill near a base,you can peer right into it and take
pics,nobody will know you did it.
Makes for a fun spy mission,and you can get some excercise lugging the stuff out there and back too.
The ground sensors will pick up the EM waves from all of that equipment, if the sound of your walking feet don't trip an alarm first.
Even driving on a public road near a restricted base is suspicious behavior that is bound to be investigated. It is an excellent opportunity,
however, to view black helicopters (plural) up close and personal.
If you are going to risk it, consider all of the possibilities in terms of technology. If the report is correct about Dulce, the working class greys
have a small box they push which can stun paralyze or kill a life form. Considering that our military technology advances 40 years per year of
Research & Development is incredible.
Do not underestimate the level of risk that you are placing yourselves in, should you decide to go through with any plans to investigate a restricted
base. I've read some news stories through google that describe folks getting hurt.
