Thank you again for all the nice compliments. The 4 wheel carriage is a Glinkowski Mini Mix marathon and the 2 wheel cart is a Missouri Flyer. I don't believe the Missouri Flyer is made anymore. It is a nice cart. I have already bent a spoke on one of the wheels going through a ditch a bit to hard...yep caught a bit of air and came down hard. I would hate to see what I could do to pneumatic tires/wheel if I can bend steel wheels. LOL. However, I do run the hazards hard and at full speed. Shay can really dig down and spin the cart...you can see it in one of the pics where he is turning hard and the inside wheel is off the ground.
