Getting around

Straight-line miles. The road is always longer, and as the book says, an interstate at 70 is a different trip from a farm road at 45. Check the real drive: Mission Regional Medical Center, Mission, San Antonio.

Hidalgo County is in a metro area of 250,000 to 1 million people (USDA rural-urban code 2, on a scale where 1 is the biggest metro areas and 9 the most rural counties).
