Potential summer sprint venues that are logistically easy for me. Yes, EMU/ U M D / Wayne would be better, maybe we'll check on those as well.
Novi elementary schools. ~2800 feet on the diagonal. Can field check every other week throughout the winter (across from basketball practice)
Plymouth Township Park A little small (just under 2000 feet north to south), but a pond + stream and a little topography, some grassy trail maze. <2 two miles from house
Plymouth Canton Educational Park. Not the most interesting, but a mile end to end. ~10 minutes away. Has mandate for public usage I think. Daughter currently taking the xc coach's civics class, curious if that helps.
