Evil Tank? Not This One
You never knew until now that there was another tank in Nashua, did you?
Finding the log on this tank should be a much easier task than finding the log on the tank across town. As a matter of fact, I would be very surprised if you did not find it. This Not So Evil Tank Of Nashua has been placed for everyone who has been to, will ever come to, or even thought about searching for the container placed at the Evil Tank of Nashua.
Just one more thing, you do need to bring your own pen.
