Here's the reply of Sir Robby re: this letter po.

"Thanks Rochelle. 

Hahaha, outdated or superseded na ito.  The letter was signed by DepEd RD San Antonio on Dec. 21, 2017 a week before DepEd Dept Order No. 66 or the "Implementing Guidelines on the Conduct of Off-Campus Activities," issued on Dec. 27, 2017 by Education Secretary Leonor Briones. The order has lifted the moratorium on field trips imposed on March 2017 through  DepEd Memorandum No. 47. I hope he will change his stand. "
