With only a little time left before the child wakes up, Santa\u2019s GPS goes down due to the storm, and his only guide is an old, hand-drawn map made by an elf years ago! What should Santa do to avoid getting lost in the snow, mistaken for a snow yeti by mountain goats, and ensure the gift is delivered on time?<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024.jpg\" alt=\"\" class=\"wp-image-437\" style=\"width:620px;height:auto\" srcset=\"https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024.jpg 1024w, https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024-300x300.jpg 300w, https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024-150x150.jpg 150w, https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024-768x768.jpg 768w, https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024-640x640.jpg 640w, https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024-24x24.jpg 24w, https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024-36x36.jpg 36w, https:\/\/control-advent.com\/wp-content\/uploads\/2024\/11\/23-Dec-2024-48x48.jpg 48w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">a. \ud83d\uddfa\ufe0f\u2728\ud83e\udddd Trust the elf\u2019s map, since it\u2019s the only thing he has.
