Wat Pa Pao, primarily services the Shan Burmese immigrant community of Chiang Mai. I attended day 4 (?) of the shin byu or novice monk initiation ceremony (shin byu (or pyu) ceremony - means to 'make a monk'). The boys, ages roughly 5-15 are dressed in finery (mimicking the dress of princes of Burma). The ceremony symbolises their passage into manhood and maturity.
They are treated as princes which means their feet are never allowed to touch the floor. Parents and family members feed and then carry the youngster around the temple. They are placed on horses (or elephants in some places) and in some cities paraded through the streets. This last bit is not part of the Wat Pa Pao initiation so I'll be scouting around for opportunities for next year.
