xela | Two quick questions for Boston folks

Unrelated, save that both involve an in-person handoff:

Gardeners: Could you use a small bottle of Pyrethrin Garden Insect Spray Concentrate? I have most of a half-pint; free to good home.
Anyone going to Canada in the near future: I have CAD125 that I'd gladly swap someone for a dollar less than whatever xe.com says it's worth in USD.
Cambridge Trust, where I've been banking for 25 years now, periodically has signs in the branches mentioning that they do currency exchange for customers, and can often do them the same day. So I didn't worry much about bringing some CAD back. It didn't occur to me that this convenience might come at an enormous premium until I walked into a branch the other day and they offered me roughly USD20 less than I'd paid for that CAD125 at my sister's credit union a week before. (And no, the exchange rate is nothing like that volatile.) I'm willing to keep it in my travel wallet til next time I go to Canada rather than take that hit, just on general principle. But if someone has a use for it soon, I'm sure I can also find a use for the just under USD100 it's worth right now.
