Crazy Ivan has been rebuilt from and is open for business from beginning to end and is even better than before. You can ride singletrack all the way from the powerlines down to the SVT. Still a few feet of duff that we're digging to gold, but all ridable. Go ride it!
Upper Ivan (the steep part below the pump track) was part of the rebuild. This section has some clay in it and can get really greasy during heavy rain or when the ground thaws after a hard freeze. The good news is that it's usually good again 2-3 days later.
