You may have something going on in the subsoil -- Rocks, stumps, hard pans, gravel beds, and the like...

One area of my own lawn wasn't coming up very well... I did some digging... I pulled out 2 wheel barrows full of big rocks and buried branches out of a 12'x 6' area... Most of it was 1/2-2" below the surface of the dirt...

Also don't overlook big trees...

I often wonder how sod farmers get the stuff to come out so nice and uniform...

You need to mow. Eventually, you are going to get a soaking rain and that 10 inch grass is just going to flop over and smother itself.

Grass doesn't always come in evenly for a variety of reasons. Just reseed the bare spots and keep it watered. You also will want to apply more fertilizer if it has been a month.

Also, don't worry too much about stomping on the seedlings. They are tougher than you think. Just don't drag anything over them (like the hose) or do wheelies as you mow.

pike,
i seeded mine 3 weeks ago and have simmilar problem. however i know the reason why i have maps of nice dense sprouts and than almost bare spots. i seeded evenly, but we had heavy rain after i did and it washed seeds into these little depressions in ground. i put more seed down and they seems to sprout and fill in bare spots.

You don't say where you live but now is a bad time to be seeding. A month ago was probably the latest you could go without losing it all to the summer heat. You do need to mow. You're going to have to suck it up and take your hits (I don't think there will be any problems). If you did not mow over the weekend, set your mower to the highest setting for the first cut. You can probably leave it there for the season considering how warm it is probably going to be soon (unless you live north of Winnipeg).

Did you have a soil test to tell you how much lime to add?

Did you have some guidance that told you to water 2x per day instead of the customary 3x for new seed?

Did you have some guidance that told you to spread topsoil?

I'm starting to get up on the stump about spreading topsoil when there is no good reason. Unless you have drainage problems, spreading topsoil is not needed. I'm looking for photos to use in my campaign to warn homeowners against the casual, repeated, use of "1/4-inch of topdressing" year after year. Here is one example of what you can get.

The crepe myrtle trees are fully 1 foot above the level of the concrete sidewalk. The owners have installed metal landscaping edging in several places to keep the soil from washing out into the street. Not only is it kind of weird looking with the mounds, but most of that neighborhood has the same issues. The result is that pedestrians cannot easily walk around that neighborhood, and the home owners have to deal with mowing that mess. Whereas this lawn is what level looks like.

Thanks all very much for the input. I don't think i'm too late to re-seed. I'm in NJ and we are still getting frost. The wife has had to cover her flowers and plants three times this week.
Anyway, if i'm guilty of anything, it may be watering too little. I watered twice a day by hand (hose), but I would literally have to stand out there for two hours at a clip to get the suggested water out there. I tried hose sprinklers, but they perform to about 20% of the coverage diameter listed on the package and I would probably need about 20 of them. I did end up mowing and I just bought more seed and fertilizer. Went with Pennigton's Sun and Shade mix this time.
In regard to the topsoil, I brought some in because a majority of the area we are planting is a long stretch where our new septic field was installed. By mid-summer last year, the soil there was a horror. Ugly hard pan with tons of small pieces of shale, stones etc. It was bad.
I'm going to mow the existing grass real tight, try again with this seed and do the best I can with the watering.

Thanks again.
