Weddingbee boards

I am newly married, almost a year now, but have been nominated to hold a bridal shower for a friend who is getting married this June. I am not the MOH, but more than willing to plan a party!  I am looking for suggestions for diffent places to hold a bridal shower anywhere from Brookfield to Madison. I am trying to think outisde the box and NOT hold it at a house or restaurant while trying to keep the rental fee slim to none.  

Also, any clever ideas for a "purple" shower?

Any ideas would be appreciated.

Thanks in advance!
