So my husband and I were planning on having our gender reveal party the Sunday of Memorial Day…

So my husband and I were planning on having our gender reveal party the Sunday of Memorial Day weekend, only because we are finding out that Friday, and the parks we thought about having it at all have the pavilions booked already. My mom is doing renovations on her house and doesn't want people over and our house is too small... Any suggestions on where to have the party? We are doing the baseball thing where my husband hits the ball and it explodes with pink or blue powder so we have to have outside access for that... Any help would be greatly appreciated! 😊
