True...but the ranch had a full time security, comm and trans detachment. It was as well connected as the WH. It didn't require a lot of logistical support when he went there. All the staff stayed in guest houses, it didn't require a huge taxpayer expense. Whenever Obama (or any Pres) travels on a random vacation to a new place, all those people have to travel weeks in advance and set everything up...it's a much bigger and more expensive undertaking.
The misconception is that when the Pres travels, it's just him and some USSS guys, but in fact it's a HUGE expensive ordeal.
