This is an email I received from Dave:

Jan,

For the fourth time this year someone has entered my plot and taken my buckets.  Sometimes they use the water and return some of the buckets.  Usually they are just placed empty back at the compost bins.
This is very unsettling with me.  I fill those buckets nightly or every other night to have air temperature water for my vine crop.  Could you please send a note out to the gardeners reminding everyone that if an item is in someone's plot, it is not a communal item.  I would think that that is common knowledge.

Thanks,
Dave
