Sorry Thumper, I missed your post so I wasn't able to get you the info in a more timely fashion.
Here is the link for the Collin County IDPA club (along with match calendar). You can get a link to the gun range from there:
Currently, the range is having legal problems since the city of McKinney annexed the land the range sits on to make it part of city limits and then passed a range ordninance designed to shut the range down. You can read about it on the website if you like.
The range is owned by a local family and they are currently battling the city in court (of course sales tax that the city collects from the range is used to sue them out of existence...)
