Thx to FB friend & reader Marie for this one!:
City Residents needed for Hatch Study $400 for 2 days. Hatch Research-in Mapkewood 314-768-2123-August 25th and 26th from (I think they said from 8:00 a.m. to 5 p.m.)
It has to be 1 year since you did a study FOR THEM. So if they ask you about recent studies only count the ones for Hatch.
