It was obvious that the road was closed... but the signs were not that visible... seen in Vancouver.

Funny sign, originally uploaded by JeBeKe.

This is Dutch, shot in Belgium by a colleague of mine. "This gate should always be closed! ... even if it's open ...".

No dogs allowed in the Death Valley, California... anyway they wouldn't survive very long. This was last summer.

Distant restrooms

This was somewhere in Yosemite, California... you shouldn't be in a hurry if you want to use the official amenities...

Closed Landscape

Nice landscape, in Whistler, BC, Canada. But do not enter.... too many hazards. You can look at the mountain but not have a walk... very strange compared to other countries like Switzerland among others.

something different from most of the other signs. I just posted this because I found it funny enough... seen in BC, Canada (in Barkerville, an old traditional village)

Dogs

a "serious" one. Picture taken in the Butchard Gardens, in Victoria on Vancouver Island, BC, Canada

Lock out auto crime

BC 2006 print 0921, originally uploaded by gugs.

This sign is clear enough. The "strange" thing about it was that it was located in a small town in BC, Canada, where the crime level is probably among the lowest in North America.

Beware of pedestrians

This could be valid everywhere. This was at a place where nobody driving a car could see it... in Kowloon

Busses

simple and clear, taxis and busses. The original thing here is that there is a specific sign for double deck busses... typical in Hong Kong, an English heritage.
