Windy columns number year arch in tent
The large green balloons were supposed to be column toppers but they would not fit this position for the columns. Windy gusty afternoon, so columns were aligned with tent poles for support and lashed to them with elastic balloons.
The helium numbers were difficult as well. Normally, indoors, a single line from column to column is used and the line is taped to the bottom of the letters or numbers. In this case the numbers were blowing over almost flat and then outside the tent. Running a second line across the top tent supports and taping it to the top-back of the numbers gave the support they needed to not blow sideways.
