Life is short,
and art long,
and decision difficult.
For those who feel compelled toward TF, where else to turn to? I admire those that can go it alone, but I realize that learning from others can open the options. Is the guild the right organization to invest into? I suggest a bit of biblical advice. How do you judge the quality of a vine? Examine the fruit. As the guild is closing in on thirty years, a long view appraisal provokes awe, in my case. Out of the guild, a publication history, a public service record, a generation of teaching and the spawning TFEC, TTRAG and TFBC. The accumulation in all the various facets would individually establish the guilds worthiness, together the guild stands as unique and precious. The single best purchase could be the Timber Framing DVD set, the root of all the various books.
Bottom line, the guild is worthy of anybodies support, regardless of personal interest.
