I do agree with Chuck - we had a fun little adventure on a cold and cloudy Saturday night. And it was quite a success. It needs a bit of tweaking, but we should be making another name for ourselves in space.com<http://space.com>again. I was surprised that Chuck's laser was so bright in a sea of valley lights. My laser was against a black background so it really stood out as bright, but Chuck was in the midst of bright lights. As he stated, to my unaided eye, his $49 and his $100+ laser looked equally as bright. Interesting, we could not see each others' lights unless it was aimed directly at each other. There was never a "I see the beam, now aim it a little to your left." Anyway, we will polish it up, get a greater distance from each other and try it again. My kids are so glad I have a hobby. -A
