The whole Hallowe'en thing seems to have made it from the USA to the UK in a big way. We now also have "maize mazes" (corn mazes), pumpkin nights, trick or treat, haunted hayrides etc etc. When I was a child, we saw just a few carved pumpkins and very few kids went "trick-or-treating". Now it's huge - parties for days either side of October 31st, hundreds of dressed-up kids out banging on doors and shops full of Hallowe'en sweets and chocolate. I very much doubt if most people under 30 in the UK have any idea of the original meaning of "All Hallow's Eve".
