      Unfortunately gps maps with trails on them are notoriously hard to come by, especially in Texas. As a hiking and trail map aficionado, I have spent many hours searching for them, with little success.

      One source I have found with some trails is http://garmin.openstreetmap.nl/
      It lets you download routable OpenStreetMap maps to your Garmin gps, and I know it includes the trails at Walnut Creek. Not sure how many it has in Williamson County though.

      Non of Garmin's maps show very many trails in Texas. And the Birdseye TOPO map IS raster, but it is scanned USGS topo maps. You can click on the link on their web page to see some examples. These maps are nice for seeing contours and creeks, but most of them are quite old, so the roads are not up to date. And they show very few trails. It does NOT include aerial maps.

      A few years ago I was able to obtain some trail data from the City of Austin and from some local cachers and mountain bikers, and created my own transparent map that shows all park boundaries in Travis County (city, county, and state) as well as many of the trails in the county. It doesn't have much data for Williamson County, but is very comprehensive for Travis County. If you can put your GPSMAP 62 into mass storage mode like I think you can, and see where your IMG files are, it should be fairly straightforward to load. It can also be added to Mapsource, but takes a bit more effort.

      If you are interested, contact me through Yahoo email and we can discuss it.

When you zoom in to a certain point, it just gets blurry-nothing like Google Maps that I thought it would be like (not to mention that the download process via Base Camp is horrendous, but that's beside the point). To add to the experience, I decided to install some free topo/trail maps that come from http://www.gpsfiledepot.com/.
      > But when caching in the field, I find me still not having the detail I need-mainly trail maps! But I just learned that the free topo I downloaded is 100k, not 24k, which would explain my topo dissatisfaction.
      > So... time to spend some money on some "real" maps. BUT, the first thing I notice is a "new" BirdsEye TOPO subscription ($30 /yr) that offers 24k imagery. My guess is, this is the "Google Maps-like" imagery I *thought* I was getting with the other BirdsEye subscription. Would this be an accurate assessment? Either way, if this is raster data, then how can they call it "topo"? Just that you see more of the topo detail? Or is there actual topo contour lines in the imagery? The description on Garmin's site is inadequate for my "newbie" brain to understand.
      > Then, it's on to trail maps. Garmin's 24k topo product ($99) states it offers trails, but so does the Rails to Trails product that only costs $10. Either way, they don't say WHICH trails, so how do I know if I will be happy with my purchase?
      > In short, if you already own these mapping products, please give me the straight dope. If not, then please help me with your best guess as to what I should expect. Basically, I want to visit nearly any semi-popular park (Lake Georgetown or Walnut Creek Metro Park, for example) and rely that my GPS will have the data I need to navigate the documented trails.
