These are 2 very good points.
Ha Ha Ha, Very good, Hoax.
This from a guy that thinks I'm wasting heartbeats by exercising. Tell you what, ride a bike for a week. You'll quit smoking, notice an increase in your bank acct. and notice your blood pressure and heartrate come way down.
Here's why "we" do this. If you take a look at any bike lane, you'll notice that this is where all of the road debris builds up. I'm not kidding, really, take a look. Kind of hard to ride over all of that without getting a flat. Solution? Call your county commission, council, state rep and tell them that they need to get the bike lanes clean as the dirt is making the riders stay in the main part of the road.
