texanfour,
Chino Hills is a nice Big League Dreams Park. I recommend that you download Google Earth (from earth.google.com-- it's free) Enter Big League Dreams, Chino Hills into the search box, and it will show you choices of BLD in Chino Hills and Riverside (termed Mira Loma in Google Earth). After you zoom in on the Chino Hills park, you can use Tools\Ruler to measure the size of the fields. You'll see that Chino Hills has one field which reaches 300 feet to center field and the other 5 are smaller.
Riverside has one field at 360 feet, and 4 other smaller ones. Both facilities have dirt infields.
So why do I mention this? Because generally, 14U games aren't played at Chino Hills. Instead they are more typically played at BLD Riverside and area high schools. And this is true even though the USSSA website lists Chino Hills as the venue. For example, there is a Presidents Day tournament next week in SoCal. USSSA.com lists 14U Major and AAA games as being at Chino Hills, but
www.baseballfirst.com, which is the website of the folks who are actually putting on the tournament, shows 14U at BLD Riverside and Washington Park in Pomona. Truth is, Chino Hills is better suited to younger players. My son played in 4 Super NITs and a few other tournaments in SoCal as a 13U and 14U player. All were listed by USSSA.com as being at Chino Hills, but he never played there.
The Southern California USSSA tournaments are well run, and feature good ball fieds. The tricky part is trying to figure out where to stay, because the possible fields are distributed over a wide area.
