Bush's ranch had permanent security facilities and did not affect other vacationers. Also, did not require near the number of security staff and local police. Could go on and on with the differences in cost to secure the POTUS at Camp David, Bush's ranch, Bush's Maine residence, Kennedy's compound, etc. These are the locations most Presidents have gone in the past 100 years. The "Western White House" Ronald Reagan. The "Southern White House", Harry Truman.
