I can relate to this heavily. Enjoy every second of it! There are fewer things in life more gratifying than helping a kid do well in something they're really into ... even if it's just driving them there and serving as ground support crew.
Enjoy that well-deserved bowl of Irish Oak and have a great evening! Here's to all the dads out there.
