Ardenwood Historic Farm Park, 34600 Ardenwood Blvd. Fremont, CA 94555: Don your kilt and spruce up your sporran for the Tartan Day Scottish Fair. I'll be selling and signing The Lost Celt at the book booth. Come to buy, put your name down for a raffle and have a chat about Celts, Cuchulain and all things tartan. It should be great fun. Little known fact, but my school uniform was a kilt…so I wore one for seven years, six times a week. (I went to school on Saturdays, too.)
