Non-cyclists might have the wrong impression of what really attracts cyclists to the sport/lifestyle/religion. Be assured that the single most important thing to carry when you are biking is a means to rehydrate yourself. And water does not ‘fill the bill‘.
The photo has a rather odd distribution of beverages. It really needs to accommodate far more cans/kegs of beer. After that we know that wine is a favorite libation. The hard stuff is great too!
Never mind that we hate it when drivers have the same ‘reasons‘ for driving around with open liquor. We seem to feel that BUI is okay because well, who could get hurt?
If you have to ask that question perhaps you need to stop drinking while you are still alive to do so. Oh and mind that pedestrian. They topple quite nicely when struck by a bicycle.
