so I stop at Radio Shack on my way home and pick up the cheapest
soldering iron they have along with a small roll of solder... get home
and I realize the solder is marked "60/40 Rosin Core Solder." Now it
doesn't say what the 60 and the 40 stand for... but... I just realized
that this is the first time i've seen same in years... have the rules
been relaxed to allow the sale of non-lead-free solder again? or did I
stumble across some old stock? Last time I bought solder was maybe 5
years ago and I couldn't find goold old 60/40 to save my life...

63/37 is the ideal mix of tin and lead.

I bought a 5 lb roll of 60/40 solder in Atlanta at a Hamfest in 1976.
I'm about 1/3 way through the roll.
