Any ideas on how to accomplish this?

Sayzer,
What is the correct distance between the two laser beams?

I did not know about deer group work!

Since Bart said that they appear standing all together, placing the laser beams at a height low enough somewhere around the tires of vehicle and also around the legs of the deer could be ok. Bart can find the correct height with respect to the ground. And if there is a group work going on, Bart’s code may also detect it! :-)

Also, considering an average vehicle speed and putting a second set of lasers somewhere after the first set (say 20 meters), can provide much much safer detect. Costs $10 extra!

- May use small pieces of mirrors and can control the entire circuit from home. No battery is needed! Remember, the range of cheap (US$2.0) laser pointers is over one mile and if you get a good quality one you get about 10miles.

Also, here is my version of social warning (modified from Melanie's)
