I haven't been on here in a while but seeing this I'm late to the party. I've followed Larry in his magazine articles for years and more recently on YouTube. Although I've been in the hobby for decades, I've only recently been getting my feet wet with DCC and last year purchased a Train Control Systems DCC system so Larry's videos have been a great resource. But I'm sorry that he will be less active but understand the situation.
Cheers,
Jim
