Les... be careful with aspirin in strokes. If you're having a bleed, you've almost signed a death warrant by taking it. However, most (about 85-90% of strokes) are NOT hemorrhagic...
Dweste, I grew up in SoCal too. Never had a problem with a knife. Everything, however, was a "mini" version, ie SAK classic or mini-benchmade (3" blade). In fact, I've never been stopped/questioned about one, except going into jails (I worked EMS, and can't take weapons in past the guards). Have you had different experiences?
