If you're in the far northern reaches, you can come by Pfluger park in
Pflugerville. The parking lot near the pool has plenty of bur oaks, I
picked up about 20 last year this time. This is the big city park,
enter off Railroad, just north of the light at Railroad and 1825/Pecan.

To answer the other question, the bur oaks around the pool don't look
like they're nearly 20 years old, and my sister has one that's not more
than 15, which has been producing acorns for years.

Hello all,

Our troop will be needing Bur oak acorns for a project. I was
wondering if any of you knew where some of the trees were growing or
if you had some acorns and caps you might be willing to share.Any lead
is appreciated! I will of course travel to pick them up or pay for
postage. I thank you in advance.
Warmly,
Leslie
