I just found out that it is National Vegetarian Week!
http://www.vegsoc.org/nvw/
Two problems:
1) it seems to be in the UK only
2) it is VERY poorly advertised. The only activity in my area is my local health food shop offering some free samples

And I only found that out from the website!
Also, it is sponsored by Cauldron Foods. I know that only a couple of their products are vegan: everything else contains egg or milk powder...
On the good side:
- I will get free chocolate when I go shopping
- In other areas there are more activities: I read that a primary school is having a day where the children discuss being vegetarian, and try vegetarian food (I am surprised they are allowed to do this - my school taught us that vegetarians were unhealthy

). Some restaurants are serving discounted vegetarian meals too.
