Gabe,
My reply is a little late,but believe that We started trading in front of the Strike Machine,where I make most of My trades. Have found the following to work very well,even if you do not need the Strike the other fellow has ,i take in trade anyway,& swap later to another Party. Have found this helps when i am stuck for a strike. Missed most Strikes since last january,& came home with all but one red,& traded for it when home. Thanks to fellow collectors. Many will ask Me for a certain Strike,and usually will find one from another collector,& make a trade.
Always have a great time,mainly seeing old Friends.
John
