There is another facility about the same distance from me and a few bucks cheaper, however the hours they are open is very limiting and I just can't see that working for me. Having 24hr secure access 7 days a week is a HUGE plus for me.

Theft is another good point and reminds me of another reason why I would like to increase my storage space. I would like to have the ability to stockpile the most valuable of items (copper, brass etc) in order to get the best possible price for my metal. Because of how small scale I am at the moment maybe I'm delusional about that but I would imagine if you can offer the yard a good amount of material they would be willing to work with you a bit on the price. Wouldn't want to have a couple hundred pounds of copper sitting around with my current situation.
