1. Every store in town- even hairdressers and real estate agents - has pumpkins in its window.
2. Every mother in town already has her child's Halloween costume sorted - even though it's still over a month away...
3. Farm shops you've never noticed before burst into riotous colour with hundreds of - you've guessed it - pumpkins, plus bouncy castles and hayride-tractors.

6. There is a severe danger of falling acorns braining you as you step out of the front door.
