Homeruns are definitely fun. My oldest hit is first in a rec game at 11, Crushed it. Only HR he every hit. Still talks about it.
youngest boy hit a lot when he was younger, first one at 9, something like 20 as a 12 year old on 200' fences. At 13 he went to big boy fields and fences, Generally 300 to hit it out. Didn't hit one until he was 16 again. 16- 18 hit probably hit 20, but there was a 3 year gap where by 15 he was frustrated. So enjoy em when they happen. But always shoot for line drives
