Cheapest place in deadwood, electric and water on site you have to pull up to the grey and black water dump. There is a trolley stop there that will take you all around deadwood. $35 a night for me
It is muddy and sites have no separation. Water and power only. On the plus side you can walk to downtown showers are newish and clean, internet is free and two bars. Price was 35 for one nite with Good Sams discount.
Stayed one night--not full hookups, no cable muddy, close sites-- would drive down to Sturgis and stay at Days End cheaper and nicer!
