Deliver Water to the Lakota

So I plan to make the trip up to North Dakota for the weekend to deliver water and offer my support for the Lakota Natives who are halting the construction of a pipeline on their sacred land. The pipeline has the potential to contaminate their main source for water, depriving thousands. 

The protesters have halted the construction of the pipeline temporarily, but the government has cut off their camps water supply. 

More Details here: http://www.telesurtv.net/english/news/Authorities-Remove-Water-Supply-to-Dakota-Pipeline-Protest-Site-20160823-0002.html

My plan is to fill my van full of bottled water, and head up to ND tomorrow. This will be a LOT of money in my big 12 person van, as well as the cost of the water. 

None of the money made will go to things like food/lodging/other travel needs. It will only go towards gas and water. 

If I do not use all the money for gas/water, I will donate the rest of it to the protesters here: https://www.change.org/f/send-native-youth-leaders-to-block-the-pipeline?source_location=petition_show

Any help is appreciated.
