Fwiw, the majority of the world just sees this and not the fun he had with his sharpie. That’ll show Canada I guess! And we still have Gulf of Mexico too, unfortunately with parentheses.

The world is talking about Airlink now, lol. Also seems they've never seen a St. Helena or Skukuza approach and landing 🙃 This was well-rehearsed, authorised, and executed as planned. There are many angles, I implore you to look at _all_ of them. Anyway, back to business as usual for ZS-YDE 🇿🇦

I think the UK should just face the fact that they need Larry as prime minister. He has a lot of experience. He is ready to serve.

The long wait for a K-40 spectrum on my Radiacode 103. I only have a pretty small sample of low salt (50% KCl). Waiting for my 200g back of pure KCl. So this might take a while… I hear muriated potash is even better but just dusty and messy:

ordering books from germany as a south african is an extreme sport
We use international Standard shipping so we don’t have tracking information. Delivery usually takes 4 to 8 business days. In a few rare cases, delivery may take up to 40 business days.
Hopefully it should be with you in the next few days.
