They don't want you to. Again park at your own risk
There has been a huge increase in car thefts and thefts of PARTS of cars (catalytic converters) and other items. Parking is always AT YOUR OWN RISK in all DART, TRE and DCTA parking lots. Take, Hide, Lock, Cover. Be vigilant.
It isn't recommended, but the lot is occasionally monitored as far as I know.
