8T,

I've been catching them on all kinds of things other than poppers so I don't think it's likely that I'm fishing in a place with no bass. However, I often fish the city park ponds or other small bodies of water (due to my lack of a boat, and yes, I still cast them inches from the opposite shore) and they probably do see a lot of stuff thrown at them, though it's probably not often they see flies other than mine.
