Adding to the potential for inebriated cowboys and cowgirls, bars and restaurants in the city will have the option of starting liquor service two hours earlier than usual, at 8 a.m. instead of 10 a.m.

Stampede party-goers who have had too much to drink have the option of purchasing discounted Calgary Transit tickets for a ride home on city buses and CTrains.

So far this year, there have been 11 fatal collisions in Calgary killing 12 people. Alcohol has been a factor in five of those collisions.

If you suspect a driver of being impaired, police ask you call 911 immediately.
