Do a lot of shooting and camping in the general area you mentioned. 10-15 miles north of Barstow (Yermo exit).
We've used cases and cases of this stuff all the time in the desert BLM. We've mixed them in their standard containers, but like to mix larger amounts for the bigger booms. Gatorade, soda bottles, & water bottles have a bigger concussion and bang. We just ordered the stuff from Tannerites website.
Never had any problems with the officials. Their only concern was keeping the area clean after we left.
We have been buzzed a few times by the CHP airplanes. Guess, they're just seeing where all the noise was coming from. We're a couple miles from the 15 FWY, but the Tannerite still can be heard from there. Must be getting calls from the CA Agricultural checkpoint to the CHP offices. They just waived the planes wing from side to side and waived at us.
