We saw these large, round, white puffs on farms all over Iceland -- I guess they grow really enormous marshmallows there! Actually, these are bales of hay, wrapped in plastic to allow the grass to ferment (a practice called "haylage"), which apparently retains more of the nutrition in the hay.
That wraps up our Iceland journey -- we stayed overnight in Keflavik and caught an early flight home the next day. Thanks for reading! I hope you enjoyed this Iceland travelogue.
