Wow...those Rovers are quite abundant where I live. I got another two today and still left about seven behind. However, why am I hoarding them? Haha. I set one free and have four carded.
Dang, now it got to me again. How about running with three carded rovers in each hand!It's Mainlineitis, the rare Martian strain.
Swallow four Real Rider tires and call me in the morning.
If fever persists, run naked through the streets with a carded Rover in each hand.
