Good points. And I'd say the best places to visit are not necessarily ruins or remote lonely beaches or anything like that but places that are bustling with people during the day but where not a soul is present at night. When I served as a conscript in the military, I actually enjoyed acting as the company duty officer in the middle of the night when nobody in the company was awake and the only people in the entire garrison awake were the duty officer of the garrison and another conscript NCO duty officer in another company. I thoroughly enjoyed the quiet because the days tended to be very busy.
