Greg has an interesting way, unique to New Mexico, of recharging his batteries. He grew up with a strong sense of local history, and one of his favorite hobbies is 'ghost towning,' where you get maps and track down old ghost towns in the New Mexican wilderness.

'It's incredible, these abandoned towns. Such hard work went into it and now nature is reclaiming everything. You come over a ridge and find a town that has been essentially unchanged for 130 years. It's a window into history. I get a sense of my own mortality. You find shoes, and books—they just up and left everything.'
