Hello,
I'm new to the forum, but thought I'd share my trick for getting free wheel weights. It is somewhat time consuming, but I can get them for free pretty much any day of the week when its daylight out.
I found that there are lots of wheel weights at the end of freeway exit ramps. I am certainly not the first person to notice this, but I have found it can be very productive. This past weekend I had my biggest find of about 8lbs of wheel weights at the end of one exit ramp. The best part is that they are often 95% or more lead! Seldom do the steel and zinc wheel weights fall off like the lead ones do.
Now, I caution you that this is not true at all exit ramps. There are some exit ramps that are better "producers" than others. I'll share some of my observations with you later if you're interested.
