Boat Storage

Here pretty quick I am going to be in the market to buy me a new to me boat. The only problem is that I can't put an 18 ft or bigger boat in my garage, so I am going to have to find a good secure place to park it. I live on the west side of Fort Worth does anyone have any suggestions

Where do you mostly fish? I just got a storage unit for my boat near Eagle Mountain. 28' x 11' enclosed with a door and lock. $100/month.
