Fogive me if I don't respond to the right person first - still trying to "get up to speed"! July 10th looks like a better date than the end of June. At this stage in the use of our park being open on the weekend is not happening. We have been known tho, to drop in and gab with friends at Goldseekers before they go out on their trip.
As far as books we tend to use 2 quite frequently right now. Plants of the Western Boreal Forest & Aspen Parkland by johnson, Kershaw, MacKinnon and Pojar ... and Wetland Plants of Ontario by Newmaster, Harris and Kershaw. Both are from the Lone Pine Press family.
