"The Blizzard be strong outside, lads; settle yehself in and breathe the steam; we'll pass the time with a story."
An ancient shrine of a mischievous goddess. The proper offering will give you her blessing, but 'ware you don't feed her wrong!
The PCs traveling along the road/path/trail begin to hear a low droning sound. As they approach they find their path obstructed by hundred of thousands of droning insects. Locusts swarm though the air, feasting on the grass and plants. Passage will be slowed, but the insects pose no threat to the party, aside from being crunchy and disgusting underfoot, climbing into pouches and eating exposed food goods.
