Never been to one...but have smelled them. They do a few weird jobs in Iowa. Corn detassleing. walking beans. Used to walk beans and pick rocks growing up In MN.
Walk beans = walking down bean field. 2 rows eeither side looking for weeds, like mustard, thistle, etc. made 1.50 hr. now obsolete? with pesticides. Not sure.
Pick rocks= In MN the ground would freeze solid in Winter, come Spring ground would thaw and rocks left from glacier pull back gazillion years ago would pop up. You had to get rocks out of field before farmer drilled land. Thats tilling land with disk behind tractor for you city slickers.
Fun times. 1.75 hr.
My Mom worked at the Elevator so I had inside track for all those great jobs. Thats grain elevator... every small town has them..
