I second that emotion! I started with a Marx outfit in the early '70s because that is all our family could afford. I got into HO in the late '70s and moved on to other interests until I was in the public library in 1982 and saw "All Aboard" by Ron Hollander. That was the beginning of the infection that has lasted ever since. I checked that book out of the library at least 10 times before I bought the softcover version and the updated re-issue hardcover version years later. I still try to read the thing cover to cover every couple of years.
I was sort of "drifting" in the years before I really got into trains and honestly believe they were a HUGE part of keeping me on the straight and narrow all these years. Thanks Ron Hollander for being the catalyst for the passion I have for all things model trains!!
