Oh man, mirrors are the worst for hiding stuff. That little lip at the top can hold a whole secret world of dust and grime. You wipe the glass and think you're done, then light hits it just right and you see the fuzzy line. Happens every time with those bathroom cabinet mirrors too.

After my own unit flooded, I switched to a basic hardwire system from Diver's Supply and it's been solid for years.

My mom's trick is a half cup of drippings and a half cup of good broth. You get the flavor without it being too heavy, and it stretches for a bigger crowd. It's the only way I've found that keeps both sides happy.

Honestly, I used to think those were a total waste. But seeing that many birds all winter? I mean, maybe it's worth it after all.
