Glad your allrite. My allerts vary on the MUP's I ride.
Along with my bell-I alternate with:"On your left!","Good morning(afternoon/evening)", "BIKING!", "CYCLING!", "HOWDY!" and sometimes nothing (just the bell). It's very difficult to tell if folks w/walkmans on have heard me unless they acknowledge-so I pass them with particular care.
On the few occassions I've seen folks on the wrong side of the trail, around blind corners-I let out a scare the crap out of anyone "TRAIL!" as I slow or stop. I think I picked up hollering "TRAIL!" from crosscountry&downhill skiing as a kid.
