What to do about it in Seminole

• A sunrise alarm clock is worth getting here: on 66 weekdays the sun is still at least 20 minutes from rising at 7:00 am. Dark mornings run from Aug 13 to Apr 21, so set it up before Aug 13.
• Daylight alone gives little reason for a light therapy lamp here. Getting outside in the 7:18 am to 5:41 pm window on the shortest day does more than most people expect.
• Heading home at 5:30 pm, you get at least some daylight all year here.
