Here is some info I received:

My name is Emily and I'm contacting you on behalf of Wheeler's
Frozen Dessert Co., a vegan & non-dairy ice cream bar in Boston.

We're traveling to LA this weekend to participate in the Great
LA Ice Cream Party, and will be the first vegan ice cream shop
to participate in the event! We would love to invite you and
the rest of your meetup group to stop by and grab some ice
cream this weekend - and if you could pass along the message,
that would be great! Here's the details for the event:
