Admittedly Easier Said Than Done
If you're first learning of Parachute over the Red Sea Day this year, you probably won't be able to celebrate it, unless you already know how to parachute and live in the vicinity of the Red Sea. So maybe you want to mark your electronic calendar for January 14 of next year and put a six-month notification on it so you can make plans accordingly.
For those who do know how to parachute and can easily and quickly get to the Red Sea, this is your lucky day!
If you're capable of doing the above, cost is likely no object. Therefore, I would suggest that you also rent or charter or buy a ship large enough to be the target of your freefall and graceful landing. It would be much drier than landing in the water.
If you know how to parachute but can't get to the Red Sea today, you can probably substitute some other similarly-named place as your destination and still count it as a proper commemoration of the day.
Red Lake, Minnesota, is the first such place that comes to mind. This Red Lake is a city, not a body of water though, so be careful there.
There is a wet Red Lake in Florida that you could aim for. There's an airport nearby, so that may be helpful.
There's another wet one in northern Wisconsin just east of U.S. highway 53 between Gordon and Lampson - so you know where that is. Yes, you do...the one in Douglas County. Yup, that one.
For overseas readers, I'll mention briefly that there are Red Lakes in Switzerland, Belarus, Norway, Romania, and Croatia. This secondary link will eventually lead you to their locations.
You're probably wondering why this is even a special day. So am I. No clue. Sorry, can't help you on this one. Just enjoy it as soon as you can.
