Went out and recorded one of Suncor Energy's three Thunderbolt 1003s. Only time I've heard the 'Bolt before was from the train station about three miles away maybe ten years ago, so I thought I'd sneak a view from the park right behind the cemetery, 100 feet from the siren! It's perched maybe fifteen feet off the ground. First impression hearing one up close, I must say it was quite impressive! Packed quite the punch even in hi-lo. My bad about the jumpy camera. :>
