Trialsguy,

Yes, the HSB certainly should survive your winters...in fact with their high sensitivity to temps above 80 degrees, one would think they would do much better in your area than here in Texas. I believe that we have seen posts from Indiana of GG's and know for sure that Bz in Minn. is doing an outstanding job with HBG. Check out this thread for his comments:
