Yes, the stars are huge in the mountains. Thin air, no light pollution. You can see how the constellations were observed. Instead of just seeing the major stars in the constellation, you can see shading from the billions of far-off stars you don't usually see.

I remember being in the NM mountains in the 70s. The stars looked positively huge because of the altitude combined with lack of light pollution from cities. We don't have bears here, but we do have mountain lions--I'm sure this would work on them, too.

I know what you mean about needing light in the country, Ann. I recently stayed in a friend's cabin in the mountains in New Mexico. He had a giant flashlight he called his bear light, because it helps him light up the bear when it breaks into the outside garbage bin. John's Super LED Flashlight would make a good bear light.

Super LED Flashlight

I'm voting for the Super LED Flashlight. Not because the inventor is a smart young guy, which he is, but because I think it's a nifty idea. Especially for someone who lives in the country like I do, where it's very dark at night, and we occasionally need a lot of light, like in emergencies (car crashes on my windy road, trees falling, etc.).

I really like the motor speed regulator, it seems pretty handy. I remember facing the torque problem with my drill machines when drilling the PCB boards in my undergrad. This regulator solves that problem.

Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools.
