You could use someone else's and modify it for your own use, like I did.

I used the mapdot from the user named "Gerard" in Ontario:

Right-click on the above image and select "Save to...."  your hard drive.   If the location of the dot suits you (it might be close enough), then go the Control Panel of this web site, and upload the mapdot image from your PC.

For my own mapdot, I opened Gerard's image into MS Paint, erased his dot, drew in my own, resaved and uploaded the new image to this website.
