Abysmal bungee mishap

So I just got back into riding and have been using my bike as primary mode of transportation to and from work.

The other day I bungees my workout duffel bag to the rack behind the sissy bar and a backpack with brand new, just received, never-worn rain suit and waterproof booties bungees to the front of the sissy bar.

I ended up thinking I blew a tire (brand new with less than 100 miles) when I pulled over I see that that the backpack fell into the rear wheel between the shock and locked my tired. After burning my knuckles getting it out to free the wheel, I discovered that the rain gear was all ruined as was the 20-year backpack.

I try to re-bungee it overthrows duffel bag, get maybe 1/4 mile down the road before realizing that it ALL fell off! The right rear turn signal arm bent into the tire and wore it down. After getting a how driver to pry it out to make it drivable, I continue on my way and had to return to the scene to retrieve what I could find of my mangled duffel bag!

Ugh!! I am going to send the rain gear back to the online retailer with done prayer thAt they will replace it for a discount. Lesson learned, get side bags or more bungee cords!
