We've used Gary Leff a number of times.
I had his old email (never a phone number) & last time he asked me not to use it.
He likes everything to flow thru his website.
Note: he had partners who work with him & you. You may not get Gary, but that could be ok (or not).
Last time I used Gary, I worked with someone else. Was not pleased with the way he worked with me, but the trip was booked wonderfully & we were very happy with the final trip & mile cost.
It is a service business. Not sure that he has the time to put into it as it grows, but I could be wrong.
