Say “You’re biking in th wrong side. You’re endangering yourself and others.” That’s it. Keep telling them. I do it to people all the time. I tell the walkers in the bike lane: “You’re supposed to be on THAT side. THIS is the bike lane.” They snap out of their daydreaming and go to where their supposed to be. No one has ever fought me on it, in case you’re worried. Speak up and educate people. Don’t rely on signs or the city to do it. You have a voice; use it. Telling people the plain facts goes a long way. Another case in point: someone was flooding our stairwells because they were washing their cars in the wrong area. I just wrote a sign telling them that they were flooding a common area and making it hard for people who live in the building. It never happened again. So instead of complaining, just plain tell people what they’re doing wrong, without getting angry. You’d be surprised how much you can direct change.

I understand your frustration, but the parks board does not work for you. This is a public space meant for the public to enjoy. Join a spin class or something; either way, just butt out.

Too many idiots to educate. Riding my bike should be my pleasure, not a second job. Enjoying the view should be my pleasure, not using my valuable time to spend it getting stress and doing what better signage and enforcement should be doing.

You're projecting. You are the one who feels entitled to enjoy the park at the expense of others because you think you're exempt from park rules. My expectations are fully reasonable. The paths around the park are one way. Riding against them invites accidents, especially given that there are narrow portions. Your arrogant ignorance and justification of selfish thoughtlessness is typical of someone spoiled and dripping with entitlement. If you and others are so lazy, selfish and thoughtless that you can't honor signage with purpose, you go to a spin class. It'll keep the paths safer from clueless idiots like you.

is a problem because of volume, there are maybe a few people going the wrong way near the rowing club, after the lighthouse almost never. Plus for that section you can easily go on the road, which is a bit nicer, except the "view", I guess.

As for enforcement, these signs are mostly informational, they're not binding. People don't tend to disobey them maliciously, except some of those horrible hippies going to the drumming circle!
