It's fixed! We were on the wrong track entirely. It sounded like all the noise was coming from the left front, but it was actually coming from the right front! The bearing was shot. In fact, my son said that there were pieces missing. But it's probably good that it sounded like it was the other side. My son (who's a mechanic) said that the brake line that broke could have blown at any time, and then I would have had no brakes!
Damummis, don't think I have to worry about ice now. It was in the 40s last night, and today was over 80! But I know years ago, I had gravel get in my tire, and drove me nuts trying to find the noise. I was able to locate it w/out taking it to a mechanic, so that was good. I would have look quite foolish if I had.
SD, the nature classes are my 4H club. I'm the leader of the nature club for this area. This year, we're studying bugs. We got a late start, so we won't be able to do as much as I had hoped to do. But, we've looked at how to tell the difference between an insect, and other small critters, the parts of an insect, some differences between similar insects (ie, moths and butterflies). Next month, we'll be looking at baby bugs, and they'll learn about instars and the different types of metamorphosis. Then, for our last meeting b4 we take our summer break, we'll be looking in the lake for insect larvae. The kids always enjoy that, but we always wait until it's warm weather b4 doing that. Then next year, we'll be studying birds.
