Rice used to be the popular good bye to toss at the couple, but is now not allowed at many locations. It is messy, and harmful to animals. Some other fun ideas are long sparklers for an evening event, bubbles are always fun for the guests, or try fall leaves, lavender buds or rose petals. The key is to find something that is safe on the environment and will not make a large mess.
The bubble good-bye.
Now you need something with wheels to whisk you away. The limo used to be the old stand-by but how about breaking out of the mold to try a classic car like a 1947 Rolls Royce from Best Car in Town.
You can't get more romantic than a horse drawn carriage. I had a couple where the groom surprised the bride with one after the ceremony, bonus points!
I've worked with Fairy Godmother Carriage Services before and they were very nice. They also have a ten person carriage to take the whole wedding party for a ride, how cool would that be!
They are located in the Salem area so you'll have to contact them to see if they work in the Portland metro area.
Then you have the newest option, but not a new idea, of the PediCab. They can carry two to three people and are all pedal power...these are so Portland! I can just see it, a line of four or more pedicabs taking the wedding party to their reception. Go to PDXpedicab to learn more.
