To celebrate in SL, you need some decor. Vickijo Rivera had her creators gather some wonderful flags and balloons and other decor for your homes at the Corner of Revolving time for you. They are all free! Just take a trip over to Ophelia sim and grab them. Step inside too to check out the rooms and rooms of furniture. All these goodies were put here by Pink Josephina and Zain Darkwatch for your taking.
Also take a look to the right side of the building for your summer beach towels and umbrellas and then run over to the left where you will find tents and fires for your camping. As you pass by on your way to the tents pick up a great picnic table with seating for four. As usual all these are free. You can hang out on the beach too, or visit the wedding shop at the mall.
