Guerrilla farming water setup

Hi, I'm wondering if anyone has ideas for watering plants that are a good deal away from my house, they are located on the side of a hill about a mile away from the nearest road and i can only vist them about every 10 days? any ideas for automated drip systems and/or water storage systems.
thanks

we used water bed mattresses for watering plants in VERY secluded areas with great success. with a gravity-feed method, it's not hard to set up a steady drip system...the only hard part is the initial fill-up. and digging the hole to conceal it was a lot of work too but once done there is very little maintinence needed, if any.

or, you can use a wick method where strips of cotton cloth or cotton rope are put into a water tank and once again gravity will bring water thru the wick and into your plants...i've never used this outdoors but have indoors and it works well but needs testing for proper amount of wicks needed.
