Hello everybody! The mister and I have set a date

May 20, 2012. The latest idea is to have an outdoor wedding, with a ceremony a little before noon and a lunch picnic reception. I like the idea of a lunch reception because : A) Edmonton evenings in May can get pretty cold and B) People are less likely to drink heavily
If there are any Edmontonian craftsters listening, do you think it's too much of a gamble to have an outdoor afternoon reception on a May long weekend? Chances are it won't snow, right?

We haven't booked any location yet, but I think it would be fun to have the ceremony and reception at the amphitheater of my favorite park in the city. It's fenced off, so you can get a liquor licence (unlike the rest of city parks). There's also a permanent tent with wind screens and tonnes of seating, as well as the use of portable tables and picnic tables. Anyway, here's a look at the possible venue:

Also, the amphitheatre is right next to a lake with paddleboats! How much fun would that be?
Because it would be a picnic, the table decorations would be much simpler. I think it would be nice for each family/couple to get a basket with their lunch and a tablecloth so that they could chose a table themselves or even a spot on the ground. No need for centerpieces! No need for a head table!
Still haven't figured out how to decorate it yet, but I know there will be many crafty parts. My mom and i will be making my dress (my grandma said she'd draft a pattern for me!) and my sister and FSIL want to tackle the cake. I know there will be other bits too, so watch this space!
EDIT: I went to a sample sale and came home with this

According to the lady I've talked to, they're not booking the amphitheatre June 2012 until the end of May 2011, so I still have to wait a while before getting a deffinate date.
I've gathered ideas from the web and have decisions to make!
#1: Boxed or basketed picnic lunch? I love the idea of collecting different styles and sizes of wicker baskets over the next year and a half and using them according to the size of family or couple or trio. It would be cute to have a table full of different baskets with names attatched to them. On the other hand, gabled boxes can also look really cute and would make the whole packing thing much easier and more uniform. One box per person instead of a basket per family.
#2: What to do for blankets? Somewhere on the web I saw someone who had made some with cheap bolts of fabric. They were all different but in her colours and she had stacks of them on the table next to the lunches. I would like to do something like that, but I'm also thinking it might be easier to get some table cloths in blue and yellow and use those as blankets.
#3: What else to put in the lunches? Sandwiches, of course (a deli we love makes the best roast beef and turkey sandwiches), but what other kinds of salads/fruits/snacks would be portable and satisfying?
