Pipes, last year was called due to poor weather, but was a good time in prior years. It's a Saturday evening in April, but leave that up to the Smeltinator guy. It's on Jones Island under the Hoan. I posted a map 4/5/18 @ 7:14 PM, go back 4-5 pages.
Gonna be tough for me this year as I no longer live in the immediate vicinity, move the Hartford.
Hope it happens this year...
