Signed up for Pier 121. Super nice. 230 a month... get what you pay for
I guess you and I have differing opinions on nice. I pay $100 less at Sunshine and have a full door to my stall as well as a full time on-duty guard that lives on the premises. Pier 121 stalls don't even have doors unless they were recently installed. Not only that, but their fees as little as 4 years ago were only around $140.
I have mine at Falcon, north on 423 just outside The Colony by Tom Thumb (I think this is the number (214) 603-2319) They also run an Iron Fab shop. outside $50.00 a month when paid in full.
