Some nice suggestions here, perhaps I should also put some due care and attention into looking for 12 drummers drumming, 11 pipers piping, 10 lords-a-leaping, 9 ladies dancing, 8 maids-a-milking, 7 swans-a-swimming, 6 geese-a-laying, 5 gold rings, 4 calling birds, 3 french hens, 2 turtle doves and a partridge in a pear tree?
However, is December really quite an empty month in terms of things to do and look out for in the wilderness
