Bug out to the storage unit. You will be in an area that is fenced, well lit and.....concrete, thin but still concrete walls.
There would be a lot of items you might make useful in the storage area. I also doubt, unless they are members here and same storage unit you're at, be a lot of people waiting to get in.
Don't forget they have security cameras. You will have a ready to go base of operations, unless it's across town.
