Proximity/Curiousity...
There are plenty of military bases in the UK.
The military DOES NOT (and I repeat) DOES NOT do military exercises over college pranks.
And don't give me the tripe about the value of souvenirs from crop circles. What's that got to do with it? People go to Disneyworld all the time and bring home souvenirs.
You think the fact that some money is being made from crop circle souvenirs explains WHY crop circles appear? I just don't see what you're getting at.
