A couple of weeks ago I found Grolsch in Wholefoods, a supermarket nearby. I bought a six-pack but a week later they didn't have it in stock anymore.
So, when I saw last week that Safeway had a stack of Grolsch beer I bought a supply that will last for longer.
Safeway is half-way on my way home from work and it was very warm the day that I found it, so it was quite a sacrifice.
But now I'm happy with my "own" beer in the fridge. Many people say that there is a difference in taste between Dutch beer in Holland and their export-variants but I must say I have not noticed such a difference, if there is one.
The United States has a large amount of beers to offer, by the way. The Ommegang brewery that I mentioned before is very promising, but there are also many small, local breweries that are called micro-breweries. A beer that I particularly like is Sam Adams, a large beer brand from Boston, as well as Sierra Nevada from California.
