Thanks, all!

msincredible, you must have sent me a telepathic message, for when I went to the bike shop to pick up my newly-tuned riding machine last night, I bought a Superflash. Wow, is that thing bright!! Almost scary, that! Same price as at Amazon. Not the least expensive thing out there, but who knows? Maybe I'll start riding after sunset/before sunrise. (heh heh heh... "before sunrise"... yeah, right! )

Kalidurga, lightless in the tunnel?? One thing I learned the one time I took my kid camping: you're never too old to be afraid of the dark!! (Other things I learned include don't pound tent stakes all the way in, and suspend bad word fines when putting up and taking down a tent. Oh, I learned so much that trip!!)

I'll have to see about walking through without lights... (I'm such a coward!)
