?????'s about running no alternator

[mustninty]

So I read on here about buying a deep cycle battery and ditching the alternator. What experiences have people on here had with this? On a side note I drive a 92 civic HB and I drive 150 miles roundtrip everyday, 5 days a week for work. I'm not using A/C but I am using the radio and I get off of work at 11 at night, so i would be using my lights on the way home.
