Wow, thanks everyone for the replies and advice! Now I need to change my "found" log post to include the warning! I would say that the one cache had a carpet of this stuff for 10's of meters around. I've never seen so much, which is why my husband didn't think it was poison ivy... it looked so common to the entire area! The trail itself is an old railway track, with the tracks pulled up, and "trail gravel" put down. Both sides flanked with this poison ivy. Maybe enough that the city should put up a warning!
I know we all got poison ivy from these caches (I was the last to arrive on the scene... "uh, guys...")
The good news... Now I finally feel confident in identifying it!!! But I'll need to wait another day or two to find out how bad the bad news is...
