A week ago about a dozen keen bonsaiists met at Nature's Way Nursery in Harrisburg PA to attend the three day seminar called Woodstock. This was the twelfth edition. See a few glimpses of the work there. This event was run by Jim Doyle and Walter Pall with the help of Jennifer Price and Brendan Lily.
If you think that you should also treat yourself for something like this I have good news: the dates for 2020 are already set: it will be from Friday, April 4 to Sunday April 5, 2020 at Nature's Way Nursery in Harrisburg PA. You can already call Jim Doyle about a seat.
