There's about 70,000 fans heading to Candlestick park this Sunday for the San Francisco 49ers' first NFC championship in 15 years. However, they better be on their best behavior with visiting Giants fans. That's the advice from Bay Area authorities.

According to the Associated Press, no warnings will be offered to unruly fans(season ticketholders have already been warned), after several Saints fans complained during last weekend's playoff game.

More cameras and undercover cops will be on hand to identify the misbehaving fans.
