I did a goggle search and this was all i could find in your area for you. i do not have personal experience with this company as i live about 4 hours away. with many beer gas places i would think that they would want you to use their tank, which would require a deposit. they may also request that you return the tank within a certain time frame. i know one company by me in fort worth does not like to have their tanks out for more than 2 months.
