Boring Sunday. Anyone know where to go watch webcams dotted around town?

Police Station of course. They will welcome you and provide lodging.

Until you can find one around here, a browse on this site might satisfy your boredom....

I trust everyone on tv has their cameras secure?

Go hang out at the intersection of the Mae Nam Ping river bridge... Just as you cross the bridge going towards the moat the Dept of Tourism has installed a HUGE TV kiosk on the right corner that shows the security cams thruout the city (between very long ads for Toyota trucks)... If it is a nice day and not too hot you can also watch the BIBs shake down motorcycles for traffic violations as this is one of thier favorite spots too! ;-)
