I am at a barn near South Riding, VA and love it. We have a sand ring with regular jumps, a small grass ring, a large grass ring with "cross-country" style jumps, and lots of trails (for the time being, development is slowly taking over).
Pasture board is $300/month, but includes personalized feedings twice/day (grain provided at individualized amounts for each horse, supplements added if supplied by owner), blanketing, fly masks put on/taken off, etc all included in that cost.
It's a relaxed atmosphere. Not many people show, or else just show for fun. A lot of us do judged pleasure rides (trail rides with obstacles along the way). There's a mixture of disciplines.
BTW, I see your profile says you're in Colorado. I moved to northern Virginia (DC metro area) three years ago after living in Colorado for 22 years - the majority of my childhood (Woodland Park), followed by my college years (Boulder) and early career (Longmont/Lyons). If you have any questions, feel free to ask.
