We at Sigma would like to offer our condolences to the family and friends of those were killed in the bombings at the Boston marathon. We also offer our sympathies and good wishes for a speedy recovery to all those who were injured in this senseless tragedy. We are grateful that the many Calgary participants and their companions were uninjured and we wish them a safe return home. We are dismayed that there are those in our midst who would do such things to innocent people who were just out to enjoy a celebrated sporting event.
