I am going to take somewhat of a contrarian approach to much of what has been said here so far. Much of that is because of my situation—I travel a LOT, and fortunately I have some control over the specifics of when I travel, though not where. Most my travel is planned about three weeks out and finalized a week out—so if I want to brighten my trips my spending some time with a pretty young lady, I need to plan that about three weeks out and firm it up a week out. I very rarely can free up several hours on a day’s notice, and I essentially never thumb through ads at the last minute to pick out someone I want to see.
I understand that will prevent me from likely ever meeting many of the ladies here, so I see those whose own scheduling allows them to plan ahead also.
Prescreening and scheduling are two very different things. I do most my screening through P411 and/or D-C, and I do not understand why a lady would not cooperatively pre-screen me through one of those sites. It is almost a must for me, because often I will drive 4-6 hours from where I will be working in order to see a lady I am interested in. The most recent lady I reviewed I literally added 700 miles to my drive in order to see her (and it was worth every mile, by the way). If I am going that far out of my way, and blocking of that much of my travel time, I do not see 30 min of her time as an undue imposition. If a lady does not reply to a pre-screening request, that essentially removes her from my list of possibilities and I move on. I will request a pre-screen when I have a reasonable expectation that I will be close to a particular lady & I decided I want to meet her. This is typically 3 to 4 weeks out, and I make it very clear it is prescreening, and I am not asking her to reserve a slice of time yet because my trip is not firm.
As to actual scheduling, I will have airline tickets in hand about a week out (assuming I am flying and not driving), and at that point I will write again and provide as much flexibility as I can in dates/time, and ask her if any of those times fit her schedule. If so, I want to lock in an evening with her because the other evenings I will fill in with working. I understand some ladies cannot do that and I have no hard feeling if that doesn’t work for them—but again, it also means that I won’t be able to see them as much as I might like to.
At the extreme end, I have scheduled up to a year in advance for special occasions—when I know I will make that trip even if it is only to see her. For me it works—with certain ladies. I have done a number of 2-month out appointments if I will be at a conference or conducting training—something I know will not change.
There are a lot of people in this corner of the world, and we all have different situations. It is great for those people who are fluid enough to plan everything at the last minute, but some of us cannot. (And it always amazes me how a lady can expect to check/hear back from references in an hour or two.)
