Photo Scavenger Hunt

I'd like a little feedback on an idea that I've been batting around for a few days now.

I've been trying to think of fun ways to get the word out about our new site - Live In Strathcona

One of the things I thought of was a local community scavenger hunt.

My thought was that instead of the old "find a box under the bench" sort of scavenger hunt, we could do a photo scavenger hunt.

So, a list of clues about specific features of Strathcona would be made up and then a time limit would be placed on the event - all entries are due by ....

Contestants would have to take pictures of the submitted clues and the first one to get them all right would win (gotta figure out what, talk to some of the local shops, etc.. about a sponsored prize)

Any feedback on this idea would be great. What do you thing? Sound like Fun?
