Son Mark visiting from Hawaii

Talked to Mark just the other night on SKYPE. He told me that he will be flying in to Portland, Oregon the weekend of March 14th and after attending a seminar he would board the AmTrac train on the 16th and come up to Tacoma. He will arriving sometime around 8:30PM.
We will have sometime together before he will return to Hawaii via Seattle.
Mark said he would like to do some hiking around the area here. I hope the weather co-operates.
