Good idea, or there could be a 2000 word essay to complete on how well you understand and intend to comply with the "Love the Farm, Leave no Trace" pledge. To be marked and graded by Emily and Michael or other family members as they see fit. Anyone getting less than, say 60% for their essay is a "no go" for tickets that year.
Yes I am being a bit tongue in cheek in suggesting this but it riles me to see the continuing mass of litter etc. If only there was a way of tracing the culprits!!
