How to say you’re from the US without saying you’re from the US. Sorry, man.
Very much got USA’d in the middle of trying to grow a business. Ended up losing basically everything and starting over in life, out of everything though, that telescope was the only thing I really miss.
Please accept this hug from an internet stranger that is likely heading down the same road… hoping the symptoms end up being a huge nothingburger, but if not then I’m going to miss my hobbyist equipment.
The good news, is after you lose everything at least once, life broadly becomes a lot less scary. Best wishes and I hope you land on your feet whatever the results.
