You can see what the security fencing was for now.
Should be a good location to make a stand, if the fences hold and they can park a vehicle across the entrance.
The entrance barrier pivots on a small length of brass rod, the rest of it is plasticard.
The roller shutters are just corrugated card, simple but I think effective.
Wooden shapes and cocktail sticks for the geothermal units here.
A perfect example of why you shouldn't order your security fencing from the cheapest supplier...
The fourth section has all the buildings painted and glued in place, I just need to finish the basing and make a couple of signs. :)
