Yesterday BA blogged about WIMPs and the CDMS lab. This lab, as the post indicates is nearly a half mile down in an iron mine. What wasn't mentioned is this is an abandoned mine, now run as a Minnesota State Park. During the summer tours of both the mine and the physics lab are offered. The lab does more than look for WIMPs. It started life as a neutrino lab. That research is still ongoing. It also does proton decay research. Only problem some folk have is the half mile ride in a rather small, dimly lit, mine elevator. It's very confining and takes 3 minutes. The lab is handicapped accessible but the mine is not. It's well worth a visit if you are in northeast Minnesota.
