There were 3 to show up for the work day on Saturday (Charley Braun, Mike Kurtz and myself). We did some more clearing on #7 and augmented the crossings you mentioned. The cinder blocks on #7's approach are a bit tippy so I recommend crossing on the bridge you see before you get to the second creek crossing.
Unfortunately, it rained Friday night, so the concrete truck could not make it down to the remaining tees. We're going to try for sometime during the week to get those last three, but the possibility remains that we throw from natural tees for 8, 9 and 10.
Now, we're just waiting for the mower to catch the lower part of #4 and the brush hog to get the 7, 8 and 9 fairways.
After surveying the erosion on #9's tee pad, I'm considering moving the tee up to the concrete creek crossing and make that a par 3. Still an interesting hole to be sure and will improve the flow of the course not having to back track.
