Well, I exerted a lot of almost non-existent energy to spray paint one wrought-iron post and erect it.  It is 63 degrees as I write this (at 4 PM) and it has been a delightful afternoon, weather-wise.  I’ll accept an “E” for effort but the project gets an “F” for failure.  I don’t have enough strength to drive the pole into the ground.  I hammered, and hammered, and ruined the top of one post!!  I put the Bluebird house on top… and the whole thing toppled to the ground!!  (Not that the Bluebird house is very heavy.)  The bar-bells have too small a diameter so I couldn’t use them to secure the post.  (But they will work for future projects.)  I drove a smaller post in the ground and have the two tied together.  Frankly, I’ll have to give more consideration (and effort) to this specific project. (If we have any wind, I fear it will topple over.) I don’t think I can dig a “posthole” because the ground is full of tree and vine roots. (But I’m not giving up!!)
