Despite record numbers clicking through the turnstiles through the first half of this year's Calgary Stampede, police say it has been a "fairly peaceful". 
A couple of interesting trends have developed early on.
The first is an increase in the number of missing persons files on the grounds.
But Staff Sergeant Rob Van Gastel of the Stampede Incident Command Team says those numbers will likely level out because Sunday was "Family Day".
He says they've seen a decrease in the number of impaired, "unwanted guest", and altercation calls.
Van Gastel says they have seen a 50-percent increase in drug calls and an increase in the number of seizures of pepper spray.
