The Stillwater pickup location is at Kelli's house.  The farm van usually gets there pretty much on time but it is smart to call Steve a bit ahead of time and find out if the van is running on schedule or not.  Most people come by a few minutes after pickup time and pick up from Kelli's garage or the cooler she has put out for that purpose.  If you aren't going to get there within a half hour of pickup time, best to call Kelli and let her know what is happening.  No worries.
