Hello!
I sent this as an email, but it occurred to me that it might be a question better posed here:

I have a problem with BN - it always seems to not get the 24k topos properly, cutting off just the part I need!

First: I am only interested in 24k maps. Larger 100k or 250k maps are useless for trail hiking, as are aerial photos.

My wife and I do alot of backpacking. I like to download a map of the area we will be visiting. I use this standard procedure: search for trail or area name. select most obvious result. disable aerial photo, and select most detail. Leave at 2.5 mile x 2.5 mile size. Download map. Result: 250k and 100k maps are great, but 24k map always has the useful area cut off!

I have tried a larger map size (say 5 miles x 5) and the results are usually about the same. I really hate the added download wait time, and giant map size (not to mention that it pretty much STILL does not contain a useful 24k map..)

In my email, I suggested a 'download 24k map data only' option, to avoid superfluous downloading of map scales I don't need.

Can anyone suggest something that will help me?
I sure want this to work...

Thanks!

I think the OP may be referring to the problem where isolated 24k tiles fail to download.  This appears to be a Terraserver problem, but it's a strange one.  At the max viewing area to see the 24k maps, some of the tiles are missing.  These are the ones that don't get downloaded by BCN. BUT, if you zoom in one more time, the tiles are there!

One place where I know this happens: 35.20628, -85.08401.  It's across the TN River from TVA's Sequoya Nuclear Plant.  At the first zoom level where the 24k maps are shown, the tile is a blank gray square.  But if you zoom in again, all the information is shown correctly.  That tile does NOT download into BCN.  I've seen this happen in tons of other places, but that's the only one where I remember the specific location off the top of my head (I don't have my PPC with me).
