I'll be in Portland, Maine, USA this summer. The Bay of Fundy is tantalizingly close yet too far on a limited day trip. Anyone know of good (non quarry) mud places along the coast, like the tidal mud? Willing to go a bit north or south (like to Boston).

Archenemys used to film their excellent quarry vids along the i-95 near Augusta, so there's definitely mud to be had. There are also a few mud events going on this summer, too: I was actually thinking of bringing Ms. Plonk down for this, but there's a women's mud-run happening an hour north of Portland on June 23rd in Minot. That'll likely have two of the things you're looking for, so dress to impress, and may the odds be ever in your favor. o7

Aside from that, Maine has a ton of clay along many of the lakes and rivers. I'd suggest you scan reddit for places ATV/off-roaders congregate:

Maine is pretty decent in summer, so you could even get some hiking in to find really good hidden pits, but bring a shotgun for the mosquitoes.
