Hi Carol,
I just found your post mentioning the Hillcrest Mine explosion. My grandpa lost 4 uncle's in that disaster as well. Next June is the 100th anniversary of the mine explosion, and the town is hosting a commemorative anniversary for it -
www.hillcrestmine100.com. 3 generations of our family are going. Since your trip is coming up in the summer, maybe it can be timed so you can be there for it?
