I 've set 3 bricks in the ground to mark my tripod position. Each brick has a "hollow" to securely hold the tripod foot. Last night I put my tripod back into position and went to do the polar alignment - it was out by only 5 arcmin - really pleased with that.
The bricks don't actually form a completely level base, but that's not critical as long as the tripod leg lengths are not adjusted between imaging sessions.
Now I must do the same for tripod 2.

Good idea Mark. I always plonk my mount in the same position on the lawn & the three pointed legs of tripod have formed small holes which tend to go rock hard in summer so like you as long as I don't adjust tripod leg height all I do is carry complete mount out & place in same position. Takes a few mins & is always very close - Used this to set up last night & was doing 20min subs (now I have sorted out the drift problem i.e. OAG).

Mine is just left out with a bucket over the mount that seems to work.
I used to have three level patches, each made using three hexagonal paving slabs. However, the worms and the grass soon buried them....
I was going to bury three beer bottles upside down in the lawn. Somehow, after I drunk the beer I forgot about the burying bit...
