Field surface: 12 turf diamonds on 3 modular pods

Synthetic turf: Oasis lists twelve artificial turf baseball/softball fields on three modular turf pods (A, B and C, four fields each). Each pod converts from four diamonds into two full-size soccer fields, so the playing surface is turf from the infield through the outfield. The complex also has two natural grass fields for other sports. (12 artificial turf baseball/softball fields, A1-A4, B1-B4 and C1-C4, on three modular pods, plus 2 natural grass fields and the Integrity Dome, an air-supported indoor turf facility (Oasis Sports Complex; KBSI; visitSI).)

Packing notes

Southern Illinois springs swing from cool mornings to warm afternoons: bring layers and rain gear.
Summer afternoons get hot and humid, and turf holds heat; bring a canopy or other shade, sunscreen and plenty of water.
Every diamond is turf, so turf shoes are a good fit.
