I read Crawford did not have accommodations for Secret Service. The house in Dallas was more accommodating for that and Laura wanted to be in the city to do things?
Sure it did. They wouldn't have allowed him to spend any time there, if it hadn't.
It is my understanding that there are several buidings on the property, besides the main house, suitable for housing the Secret Service, and other guests. In fact, I think, the Secret Service stayed in what had been the original home on the property, before Pres. Bush and Laura built the new, main house. That 4000 or so Sq. Ft. new house is the one that has lots of very environmentally friendly features. Pres. Bush LIVED the conservation movement, unlike that blowhard hypocrite, Algore, who lives in his fossil fuel guzzling 10000 sq. foot house in TN, buying his 'indulgences' from the Church of the Environment, while preaching that everyone ELSE should reduce their lifestyles.
