Outside on public land, Aktion Zone's Indoor Field in Meridian, Idaho & Aktion Zone's old field in Sand Hollow, Idaho.
Review:
The field is fairly new and the owners are still learning and developing the place It is very promising. It has about 100 acres with woods, a big pipe field (hyperball field), a spool field (speedball field), a small river, and a castle with more things going up all of the time. The owners are very friendly and are concerned with everyone being safe and having a good time. The prices are reasonable. The owners are open to suggestions and I expect to see this field take off fast.
It is a little drive from Boise but it worth it. Be sure to get directions before you leave, as it can be a little tricky to find.
DO NOT confuse this field with Aktion Zone in Meridian, Idaho. Aktion Zone sometimes runs scenario games at this field, but does not own it. Aktion Zone is VERY poorly managed (see the reviews on it for details) and I do not expect Aktion Zone to remain in business much longer unless major changes are made. I hope to see big scenario games run at this Ontario field soon that are run by someone besides Aktion Zone.
A good field. Some improvements need to be made (like bathrooms), but the owners are making improvements as fast as they can. It is worth a little drive to play this field.
