The labor day trajedy... Out riding my bike yesterday with the push trailer attached and got about 2 miles from my house and the chain jumped off the axle sprocket. Did not have any tools with me, all I would of needed was just one adjustable wrench to loosen the pillow block bearing and put the chain on and retighten it.... but I did not even have that! The last two miles was up quite a STEEP hill and let me tell you when you are pedaling yourself, a bike, and a 60 pound trailer in 90+ degree temps....it was tough! The point...... I will NEVER go out again without a tool bag!
