There's only about 7 of them, I'm sure it wouldn't be too much work to save the coordinates you need.

The ones that spring to mind:

Juniper Hollow
*Angel Pine
Around from Angel Pine
*Valle Occultado (teepee motel near el quebrados)
El quebrados
SF near SFPD
LS near LS airport
LS in temple
LV near baseball stadium
LV across from 4 dragons
South-East LV
Dillimore
Montgomery
*Fort Carson

* = Unused

Can't think of any more.
