I live really close to the spot where I found this one. Will definitely try to collect a series of them this summer and see if we can figure it out.

If it isn't Arctosa, Allocosa parva is the first one I'd compare to, the location fits well with the range, the part of the description I can compare to fits: "Carapace orange brown to dark red brown, usually with extensive, pale median band and submarginal bands, moderately densely covered with setae. Sternum orange, often with 3-5 pairs of black spots laterally. Chelicerae dark orange red. Legs orange or orange brown, moderately setaceous; femora each with 3 or 4 incomplete, black rings, and tibiae (and sometimes basitarsi) with 2 or 3 such rings. Abdominal dorsum yellow orange, minutely spotted with black; venter yellow orange, sometimes with few small, black spots. ...A. parva appears to tolerate somewhat dry habitats, being found in grasslands, in cavities beneath stones, in leaf litter, and occasionally in buildings. Males have been collected from February to October, and females from February to November." There's three examples on BOLD, it looks similar to one of them, the other two are so dark I can't tell if they're even the same thing.
