The point is that if you find the park with the plane, it is a short walk to the store in question.

I have just returned after successfully buying Nembutal in Santa Cruz, Bolivia. I chose this city since there is a direct flight from Europe.
To buy Nembutal was easy. The key to success was to find an Agroveterinaria. They are different from an ordinary veterinaria. They are all located in the street 6 de Agosto (just east of the city center).
This street is close to a small park with a natural size airplane. If you find the airplane you can not miss the shops. They only had one bottle Halatal in the shop (50 ml). They gave me a chair and asked me to wait while they fetched more. Five minutes later they came back with four 50ml bottles Halatal for me. And no questions.
The problem was the customs at the airport Viru-viru in Santa Cruz. This was when I left Bolivia. My handbag passed the ordinary scanning without problems. Then there was the drug control.
They opened all handbags for manual inspection. The lady found my bottles of Nembutal. She asked ‘Medicina?’ I said ‘yes’. She nodded and put them back.
Then there was stage two. All had to put their handbags in a row on the floor. Then came a dog. It did not react on my bag.
