Should Hillary make a commercial where she's in full camo pant suit dodging sniper fire?
Haven't seen bikes with studs, but it makes sense. I've seen a bicycle with studs. You can get heated gloves, clothes etc. incidentally, like for snowmobiles.
Has it ever been vacuumed out. Dust may be caught in it making it malfunction. If that's not it maybe you need a new smoke detector
There . and tell them exactly what you are looking for. They can get you a price and you'll have your new lenses very soon. They don't have their eyeglass collection online yet (it's an old compnay, but new to the world of online sales) but if you find a frame that you want, you can tell them the make and model and they will order it and sell it to you for wholesale prices. Good Luck!
