new mexico water

SO we got to new mexico tonight and went to dinner...we came back to the hotel and my roomie hannah said she was going to take a shower...next thing i know she is yelling "dudley the water is coming out brown" haha...so great water comes out of the faucet here!! lol...I guess because Mexico is attached to the new the water is brown? it eventually became clear after about 20 seconds but thats still not so good!!
