I live in MN. The electric snow blowers (2 stage) from ego work extremely well. I can only assume their riding mowers also work but my yard isn't big enough for one. I have an electric push mower and it works great. Yard is half acre. The only problem right now is price for the larger equipment. Hopefully prices drop each year.
This was nuts. I am a developer of mainly enterprise applications and sites. This game is pretty much entirely math. Incredible what they accomplished.
