I have had that before. Just once. And we don't live in the country per se, but we are in the 'Burbs. Found a bunch of critter poo with seeds. Fortunately no damage to the engine. Cleaned it up sprayed with Clorox and they never came back.
Life is short, Break the rules, Forgive quickly, Kiss slowly, Love Truly, Laugh
uncontrollably, And never regret anything that made you Smile.
