A short walk through the park will bring you to a very obvious location. Finding the actual container may take a little longer though.
A small container hidden in a park near a police station. If you time it right, you can see the helicopters land and take off. We were taking co-ordinates and were caught by surprise when two helicopters flew right over our heads to land! Hence the name. There may be a few muggles walking through the park so a little stealth is required.
