thank you laurenmarie.

Yesterday, I went to a place. It was a crowded area. As soon as I arrived there, there my friend called me on my mobile and asked 'where are you?' I replied 'I just arrived at a crowded area.'

yesterday i went to a place. It is a crowd area. As soon as i reached there my friend called over mobile and asked me where are you ? So i replied him as " i just came to a crowd area." i think now you will understand me.

Not quite - I assume you mean: I just arrived at a crowded area.

nope. I cannot tell what you mean. Can you say it differently?
