Temporarily MIA???????

Hi guys. I’ve gotten to know a few of you during my time on this forum. This is slightly off-topic but is connected to this forum. Model Grandpa has been absent for a while and I just wanted to know if any of you know if he is OK or just taking a little well deserved R&R. Sent him an e-mail a few weeks ago but got no reply. Hope he is OK. Any help would be appreciated. Thanks.

Jim
