I have been out to EDRA. I have wheeled two of the jeep trails and stayed at the bottom camp.
I live in Sheffield.
To try and answer a few of the other questions I read in this thread and to give everyone some info:
Sheffield is about 20 miles from TMTC's EDRA.
Population 200.
GAS - There is one gas station that sells sodas, beer, ice and a few snacks.
Hours are M-F 6:30 AM - 7:00 PM & Sat 12:00PM - 6:00 PM. Closed on Sundays but have been talking about opening for a few hours. The gas pumps do not have the credit card machine on them so once the place is closed you can no longer buy gas. I do believe they take credit cards inside during regular hours.
FOOD - There is one place to eat called Gloria's Kitchen (600 Southern St) It's on the corner of Avenue H and Southern St. There are about 6 tables under an porch were you eat. I will have to get back to you on the hours but the phone number is 432.836.4631
BAR - There is a bar were the locals hang out but it's BYOB as they do not have a TABC license yet...they are working on it.
Post Office - There is one Post Office in town M - F 8-5
County Pool - There is a county pool that is open during the summer months.
PARKS - There are two parks in town with swings, picnick tables, and B-ball court.
ROADSIDE PARK - Traveling towards Sheffield there is a large roadside park with 3 tables about 8 miles from TMTC's EDRA. It has plenty of room and a killer view of the area. WORTH THE TRIP!
FORT LANCASTER - This old fort is located about 10 miles from TMTC's EDRA going towards Sheffield.

The Pecos River runs through this area but there is no access other then through private land.
I will update more if need be or answer any questions.
