Hi Keith,

Thanks for the paper and help in toning down Mike's efforts to put a
stake in the Esper heart. I quickly read the paragraph you mention.
Undoubtedly part of what is said is true, but it doesn't explain it
all of the differences between the original MBH reconstruction and
any of the other NH recons. Now that Mike has moved on to a totally
new NH recon, I suppose all of this is a mute point. However, your
Blowing Hot and Cold piece clearly showed that the MBH estimates were
undoubtedly deficient in low-frequency variability compared to ANY
other recon. Enough said. I need to enjoy myself.

>>In this next round of changes I encourage everyone to make specific

>>I will incorporate the suggestions from this upcoming round into a
>>manuscript to be submitted. After review, everyone will get a crack
>>at it again.
>>I will not detail every change made (if anyone wants the file with
>>the changes tracked I can send it). Here are the major changes:
>>1) removal of mixed-hybrid approach and revised discussions/figures
>>2) removal of CE scores from the verification tables
>>3) downscaling of the Esper comparison to a single figure panel and
>>one paragraph.
>>4) revised discussion of spatial maps and revised figure (figure 8).
>>5) seasonal comparisons have been revised
>>Several suggestions have been made for where to submit. These are
>>listed on page 1 of the manuscript. Please indicate your preference
>>ASAP and I will tally the votes.
>>I would like to submit by late July, so if you could please get me
>>comments by say July 15 that would be great. I will send out a
>>reminder in early July. If I don't hear from you by July 15 I will
>>assume that you are comfortable with the manuscript.
>>Please let me know if you have difficulty with the file or would
