If there are changes that happened along the way with these rules, then I am sure that people involved would react to those. Their reactions are all normal and we understand why they feel that way. Perhaps, the access to Tsuut'ina Nation might be an issue for them and changing it could spark reactions from people involved. Well, I just hope that one day, this issue will be addressed and solved because the issue is quite big, I am pretty sure it be alright if both parties are willing to solve it.
We are a hard working bunch of your neighbours!
