I am a huge fan of drip irrigation. it is just plain all aces as far as I am concerned. I have numerous systems setup and all set on timers, and have done it for years. Some people look down at the dry season, I am happy for it, because with using specific placement drip irrigation, the plants get watered fine, but weeds do not. I am somewhat sad when it rains honestly. I also have a large cistern that my gutters run into that collects rain water. not sure how large it is, but probably at least 1-2,000 gallons. It works out pretty well.
I do not have raised beds per say for my main gardens, but I do a lot of container growing, which is a raised bed in a way, but just a simple waterline, hookup and a tap with a drip irrigation on the end and I can put water wherever I want it, real easily.
