Though the rule book section for Peas says "to another space in the Compost Area" not to "any other space in the Compost Area".
"Another" does not usually equal "any other".
So in this case read the word "another" to mean "any other", just as long as it is in the Compost Area.
Umm, exactly how does "another" not equal "any other"? Please provide an example sentence for evidence of that.
