What's the best way to end a scavenger hunt?

Question

I'm hosting a Photo Scavenger Hunt in a few days. I have a long list, and a good ammount of people attending. It will last 3 hours.

I just don't have any idea how to end it and determine a winner. Like, first team back? But I want it to be fair. I need some people with really creative minds to help me out!

I did this one other time, and we played for points, but it took over an hour to add up all the points so I don't want anything like that.

Please help!! :)

Well, how about if the teams both find everything then you can do a Tie-Breaker one? This happened with me and we did a Tie-Breaker. First one back with the photo wins!
