For those of you either in Souther Ontario, or close enough to make the drive from the US, you should check out the Canadian Warplane Heritage Museum in Hamilton, about a 45 minute drive from Niagara Falls, NY. They have several fully functional warbirds going back to WW1 and they regularly take people up for flights. Here's the price list. If you're Canadian, most of the fee can be deducted from your income tax because it counts as a charitable donation. For $2000 Canadian you can fly on one of the two remaining airworthy Avro Lancaster bombers in the world. $275 will get you a flight on a Harvard or Stearman (without all the other membership stuff listed on this page)

Whenver the Lanc flys over Toronto, the sounds of those 4 Merlins sends shivers down my spine. There's nothing like it.
