Bay seniors whose grandkids are not sure what a sleigh is, might want to check out a more updated version of Santa’s transportation choices at Hiller Aviation. This Saturday, December 2, Saint Nick will be arriving at 10 am by helicopter. There will carols, cookies and candy canes to remind you that a few holiday traditions are still sacred. Free. The Museum itself is a treat with over 40 exhibits tracing the history of aviation back to 1869. Who knew?
