I encourage people who want to see an easy safe short walkway to get the word out and get your friends to sign this petition too. I am of course assuming that your friends will also want a nice short walkway so that they can visit you easily. 

If we do not say anything the URA will simply build whatever they see fit. And that might not be suitable for public use at all.

If only a few people complain, the URA will simply ignore them.

Don't complain in private. Do something about it. Make your voice heard.
