While out and about on Friday, doing some almost-last-minute shopping, I was able to find a few more Tron cycles at Toys R Us. I picked up two more Kevin Flynn retro cycles. They were even on an unmarked sale so ended up being about $3 each. At that price, I also picked up another Clu Sentry cycle and another Sam Flynn cycle. So I should be in a good position for a light cycle game.
I was also able to get another Sam Flynn at London Drugs for about $4. While I would be happier with a few more figures, that should give me a good half dozen to use.
