I started in RC back in the mid 80's.  But i didnt do anything from 94 till 2002.  Then I built a GP PT60 and flew it around 6 times before I stopped again ( life in general got in the way).  I am semi-retired now and have lots of time to get back to RC.  I found RCU around a week ago and I love it.  The wealth of info here is amazing.  I have spent many hours this last week reading and learning.  I started a tread on my wekest link, covering, and the people have responded beautifully.  You are so right about who may be reading a posting.  About 99% of the postings I have read have been positive and informative.  With 1% sounding like someone was having a bad day.  But that 99% made t a fantastic site for the hobby.  
Great story about your dad.  Reminded me of the times I would give my dad tours of the hanger I worked in.  Welcome back to RC!!
