We're going back next Thanksgiving week, if there's another launch I hope it's during the day and I can get closer. At 20 miles away the sound took a good 1.5 minutes or so to reach me!
I eat a lot of fish, and I've found that you can save a fair chunk if you get it on offer - our local Stop and Shop regularly sells it at about 40% off as it starts to approach its sell-by date, and it's still perfectly fine at that point.
