I'm intending to get to Leadville this weekend for Ski Joring.
As for next weekend? I wouldn't want to go past Leadville, but I would consider something along the I-70 corridor. I don't know many places, though. There are a couple of places in Idaho Springs, but I'm not allowed to spend any money there. (Long story.)
There's a restaurant or two in the parking lot near the City Market on the hill outside Dillon, but I can't remember what they are. They might be good for parking and access, if someone can help me refresh my memory.
