The day I discovered a quartz vein full of crystals

 When I was young, there was a place where every time I go there, I found some small quartz crystals and druses. Years later, I remembered about it and decided to have a closer look in the surroundings of that place. In a pine forest, I've found large cracked quartz blocks that are part of a quartz vein. Look below:

Can you see the cracks in the rock and imagine what is inside them? Yes, druses and double-terminated quartz crystals! That was for sure one of the happiest days in my life. For me, it was like finding a treasure. I have returned to the place some days later with my best friend and better prepared with tools to collect some of the best I can.

Below you can see some specimens:

That was the first time in earth history that those crystals seen the day light!

Now, some more years later, looking at a geological map (in the times I have found the vein I didn't have knowledge about geological maps), I can find that there is registered a quartz vein exactly in that place, so, one thing I can recommend you is to look at existing geological maps before you go to search for minerals and so you could be more productive by searching in the right places.
