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.
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. http://www.visitfortlancaster.com/index.aspx?page=8
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.
