My husband and I are currently planning our trip to Italy in November. We'd like to go truffle hunting and we're hoping to find a recommended tour, town, or festival we could attend in late November.
That sounds delightful--this will get you started.

Alba is wonderful--truffles AND chocolate (the entire town smells like chocolate from the factory).
