My son and I collected three alternas on Juno Road in the same evening in June of 2004. All three were at or near the north s-curve. One of them, a juvie female, passed away soon after we brought her home. However, the adult male and female produced for us last year and this year with 7 and 9 hatchlings, respectively.
During late spring of this year we had another multiple alterna night on Juno Road! We scored a male and a female. They are both just under 30 inches, and we ahould be able to breed them next year. The male was found at the historical marker just south of Baker's Crossing, and the female was found exactly four miles north of Baker's.
It is interesting to note that on both of the evenings we scored multiple alternas, we saw no other snakes. We have learned that on that road you just hang in there. The five were caught at the following times: 9:05 pm, 1:54 am, and 1:58 am (2004) and 12:04 am and 12:38 am (2007).
If you want, we can post pic of the two pairs of alterna. Two are dark (males) and the females are light. One of the females has a black head (four miles north of Baker's).
