I know it was just luck after hearing the laments of so many scouring the world for crypts or finding sparse scrap iron at the crypts they did find. One thing I almost missed was that every bit of 'muddy scrap pile' could hold scrap iron even if it was the size of a tomato.

Just to rub it in the 2 crypts were a short walk (less than a minute) back to an established base.
