A note for future shelter use: bring the biggest (widest) twin mattress you can find (park doesn't provide mattresses or bedding), bring extension cords so you can reach your phone while it's charging, and bring a small table on which to set things that are plugged in 4 feet above your head! :)

Falcon is near Zapata and Roma. Zapata is a county seat; its new courthouse is built to look old and gorgeous (most newer courthouses are modern-looking). Zapata has grocery stores, restaurants, antiques and other places of interest.
Roma is closer, but is much smaller with fewer amenities. However, Roma does have it's own World Birding Center and between Roma and Falcon are at least 2 more renowned birding sites. Roma's old part of town is lovely, but not well cared-for.
