Can anyone correct errors of writing my brother?

Last summer, I went with my family to spend the holidays. On the way, we saw as police that checked cars searching for drugs.The trip made me very largoFor to go ,because to go to Albacete it takes an hour and a half.
One day, we went to Albacete to see the enclosure of the bulls at the San Fermin campo.is like.
Below Next, we climbed over a wall to see how the metian Bulls ptowb.  We saw a field opposite of my uncle with his moto.to see how to put The bulls.  After seeing the bulls was where my uncle escaped.
My uncle fell off the bike and ran in fright at the end he managed to catch the bull and rei encerrarlo.Me more than ever.

" that sought to see if there were drugs in the cars", This doesn't make sense. English speakers don't really talk like this.

"fright" more common word would be, fear

"Largo" I replaced this word because it is another word that natives don't really use unless they are in a essay compition.

Green highlights mean that I do not understand what you are saying at all, so I can not really correct it.
