When the nearby road was SH1 I would drive past this structure often, and occasionally stop and think about how one might place a cache here. But ultimately it was always pretty busy with muggles, so I was put off.
Now that this road has become much quieter, I think it's almost criminal not to have a cache here, so here it is 
Remember to do the T-Rex wave whilst here. If you don't know how to do that, ask a small child 
Things to know:
This is private land, but the cache has been placed with permission from the owner.
You do NOT have to go within the wooden fence around the structure. The cache can be reached whilst standing on the gravel in the carpark.
PLEASE replace as found, the right way up etc.
There is no room for SWAG or TB's – please bring your own scrawling device, and suitable length arms to use it 
I welcome all feedback, so please feel free to drop me a line with your thoughts on this cache.
