You need to do whatever you have to, to spend time with your dad. My dad and I were very close. I was lucky and got to work with him for the last 3 years of his life. We spoke every day, if we didn't see each other. When he started archery hunting, he still came to modern deer camp with me just so he could be there. When he died in my arms, all that time we spent together wasn't even close to enough. After your dad is gone, you can't go back and spend time with him, so do it now, while you still can.
