Winter Blast. You must first be a member of Western Pyro. (Those who have access to the Lounge may have seen photos of me holding explosive devices. They are from Winter Blast.)
(Jumped the video to the bow ties, but it’s all good.)
You can blow shit up legally! And watch others’ wild inventions. You can even build your own shells and fire them down on the line.
There’s also PGI, a similar affair but worldwide. Ned Gorski and his crew shoot stuff at the PGI shows.
Full Gorski build of an Italian-style 6-inch salami shell:
One last thing, if you don’t want to go to the trouble and expense of membership, you could save yourself something like $800 and just go to SARA Park (in Lake Havasu City, AZ) during the Winter Blast shows and sit in the stands with the public. I think they might charge $5 or something to get in. I can tell you that being behind the scenes is way better, but you really can’t find a better pyro show in the Western US.
It easily beats BM for the pyro, unless you’re in it for the huge fireball alone.
